MUI-Datatables - Datatables for MUI (formerly Material-UI)

MUI-Datatables is a responsive datatables component built on Material-UI. It comes with features like filtering, resizable columns, view/hide columns, draggable columns, search, export to CSV download, printing, selectable rows, expandable rows, pagination, and sorting. On top of the ability to customize styling on most views, there are three responsive modes "vertical", "standard", and "simple" for mobile/tablet devices.

Version 3 has been released! You can read about the updates here!

Usage

For a simple table:

1
2import MUIDataTable from "mui-datatables";
3
4const columns = ["Name", "Company", "City", "State"];
5
6const data = [
7 ["Joe James", "Test Corp", "Yonkers", "NY"],
8 ["John Walsh", "Test Corp", "Hartford", "CT"],
9 ["Bob Herm", "Test Corp", "Tampa", "FL"],

API

<MUIDataTable />

The component accepts the following props:

Name	Type	Description
title	array	Title used to caption table
columns	array	Columns used to describe table. Must be either an array of simple strings or objects describing a column
data	array	Data used to describe table. Must be either an array containing objects of key/value pairs with values that are strings or numbers, or arrays of strings or numbers (Ex: data: [{"Name": "Joe", "Job Title": "Plumber", "Age": 30}, {"Name": "Jane", "Job Title": "Electrician", "Age": 45}] or data: [["Joe", "Plumber", 30], ["Jane", "Electrician", 45]]). The customBodyRender and customBodyRenderLite options can be used to control the data display.
options	object	Options used to describe table
components	object	Custom components used to render the table

Options:

Name	Type	Default	Description
caseSensitive	boolean	false	Enable/disable case sensitivity for search.
confirmFilters	boolean	false	Works in conjunction with the customFilterDialogFooter option and makes it so filters have to be confirmed before being applied to the table. When this option is true, the customFilterDialogFooter callback will receive an applyFilters function which, when called, will apply the filters to the table. Example
columnOrder	array		An array of numbers (column indices) indicating the order the columns should be displayed in. Defaults to the order provided by the Columns prop. This option is useful if you'd like certain columns to swap positions (see draggableColumns option).
count	number		User provided override for total number of rows.
customFilterDialogFooter	function		Add a custom footer to the filter dialog. customFilterDialogFooter(curentFilterList: array, applyFilters: function) => React Component
customFooter	function		Render a custom table footer. function(count, page, rowsPerPage, changeRowsPerPage, changePage, textLabels: object) => string| React Component Example
customRowRender	function		Override default row rendering with custom function. customRowRender(data, dataIndex, rowIndex) => React Component
customSearch	function		Override default search with custom function. customSearch(searchQuery: string, currentRow: array, columns: array) => boolean
customSearchRender	function		Render a custom table search. customSearchRender(searchText: string, handleSearch, hideSearch, options) => React Component
customSort	function		Override default sorting with custom function. If you just need to override the sorting for a particular column, see the sortCompare method in the column options. function(data: array, colIndex: number, order: string) => array Example
customTableBodyFooterRender	function		Render a footer under the table body but above the table's standard footer. This is useful for creating footers for individual columns. Example
customToolbar	function		Render a custom toolbar function({displayData}) => React Component
customToolbarSelect	function		Render a custom selected rows toolbar. function(selectedRows, displayData, setSelectedRows) => void
download	boolean or string	true	Show/hide download icon from toolbar. Possible values: true: Button is visible and clickable. false: Button is not visible. disabled: Button is visible, but not clickable.
downloadOptions	object	see ->	An object of options to change the output of the CSV file: filename: string separator: string filterOptions: object useDisplayedColumnsOnly: boolean useDisplayedRowsOnly: boolean Default Value:{filename: 'tableDownload.csv', separator: ','}
draggableColumns	object	{}	An object of options describing how dragging columns should work. The options are: enabled:boolean: Indicates if draggable columns are enabled. Defaults to false. transitionTime:number: The time in milliseconds it takes for columns to swap positions. Defaults to 300. To disable the dragging of a particular column, see the "draggable" option in the columns options. Dragging a column to a new position updates the columnOrder array and triggers the onColumnOrderChange callback.
elevation	number	4	Shadow depth applied to Paper component.
enableNestedDataAccess	string	""	If provided a non-empty string (ex: "."), it will use that value in the column's names to access nested data. For example, given a enableNestedDataAccess value of "." and a column name of "phone.cell", the column would use the value found in phone:{cell:"555-5555"}. Any amount of nesting will work. Example demonstrates the functionality.
expandableRows	boolean	false	Enable/disable expandable rows. Example
expandableRowsHeader	boolean	true	Show/hide the expand all/collapse all row header for expandable rows.
expandableRowsOnClick	boolean	false	Enable/disable expand trigger when row is clicked. When False, only expand icon will trigger this action.

Customize Columns

On each column object, you have the ability to customize columns to your liking with the 'options' property. Example:

1const columns = [
2 {
3  name: "Name",
4  options: {
5   filter: true,
6   sort: false
7  }
8 },
9 ...
10];

Column:

Name	Type	Description
name	string	Name of column (This field is required)
label	string	Column Header Name override
options	object	Options for customizing column

Column Options:

Name	Type	Default	Description
customBodyRender	function		Function that returns a string or React component. Used to display data within all table cells of a given column. The value returned from this function will be used for filtering in the filter dialog. If this isn't need, you may want to consider customBodyRenderLite instead. function(value, tableMeta, updateValue) => string| React Component Example
customBodyRenderLite	function		Function that returns a string or React component. Used to display data within all table cells of a given column. This method performs better than customBodyRender but has the following caveats: The value returned from this function is not used for filtering, so the filter dialog will use the raw data from the data array. This method only gives you the dataIndex and rowIndex, leaving you to lookup the column value. function(dataIndex, rowIndex) => string| React Component Example
customHeadLabelRender	function		Function that returns a string or React component. Used for creating a custom header to a column. This method only affects the display in the table's header, other areas of the table (such as the View Columns popover), will use the column's label. function(columnMeta : object) => string| React Component
customFilterListOptions	object		(These options only affect the filter chips that display after filters are selected. To modify the filters themselves, see filterOptions) render: function that returns a string or array of strings used as the chip label(s). function(value) => string OR arrayOfStrings Example update: function that returns a filterList (see above) allowing for custom filter updates when removing the filter chip. filterType must be set to "custom". function(filterList, filterPos, index) => filterList Example
customHeadRender	function		Function that returns a string or React component. Used as display for column header. function(columnMeta, handleToggleColumn, sortOrder) => string| React Component
display	boolean or string	true	Display column in table. Possible values: true: Column is visible and toggleable via the View Columns popover in the Toolbar. false: Column is not visible but can be made visible via the View Columns popover in the Toolbar. excluded: Column is not visible and not toggleable via the View Columns popover in the Toolbar. See also: viewColumns and filter options.
download	boolean	true	Display column in CSV download file.
draggable	boolean	true	Determines if a column can be dragged. The draggableColumns.enabled option must also be true.
empty	boolean	false	This denotes whether the column has data or not (for use with intentionally empty columns).
filter	boolean	true	Display column in filter list.
filterList	array		Filter value list Example
filterOptions	object		These options affect the filter display and functionality from the filter dialog. To modify the filter chips that display after selecting filters, see customFilterListOptions This option is an object of several options for customizing the filter display and how filtering works. names: custom names for the filter fields Example logic: custom filter logic Example display(filterList, onChange(filterList, index, column), index, column, filterData): Custom rendering inside the filter dialog Example. filterList must be of the same type in the main column options, that is an array of arrays, where each array corresponds to the filter list for a given column. renderValue: A function to customize filter choices Example. Example use case: changing empty strings to "(empty)" in a dropdown. fullWidth (boolean): Will force a filter option to take up the grid's full width.
filterType	string	'dropdown'	Choice of filtering view. Takes priority over global filterType option.enum('checkbox', 'dropdown', 'multiselect', 'textField', 'custom') Use 'custom' if you are supplying your own rendering via filterOptions.
hint	string		Display hint icon with string as tooltip on hover.
print	boolean	true	Display column when printing.
searchable	boolean	true	Exclude/include column from search results.
setCellHeaderProps	function		Is called for each header cell and allows you to return custom props for the header cell based on its data. function(columnMeta: object) => object Example
setCellProps	function		Is called for each cell and allows to you return custom props for this cell based on its data. function(cellValue: string, rowIndex: number, columnIndex: number) => object Example
sort	boolean	true	Enable/disable sorting on column.
sortCompare	function		Custom sort function for the column. Takes in an order string and returns a function that compares the two column values. If this method and options.customSort are both defined, this method will take precedence. (order) => ({data: val1}, {data: val2}) => number Example
sortDescFirst	boolean	false	Causes the first click on a column to sort by desc rather than asc. Example
sortThirdClickReset	boolean	false	Allows for a third click on a column header to undo any sorting on the column. Example
viewColumns	boolean	true	Allow user to toggle column visibility through 'View Column' list.

customHeadRender is called with these arguments:

1function(columnMeta: {
2  customHeadRender: func,
3  display: enum('true', 'false', 'excluded'),
4  filter: boolean,
5  sort: boolean,
6  download: boolean,
7  empty: boolean,
8  index: number,
9  label: string,
10  name: string,
11  print: boolean,
12  searchable: boolean,
13  viewColumns: boolean
14}, handleToggleColumn: function(columnIndex))

customBodyRender is called with these arguments:

1function(value: any, tableMeta: {
2  rowIndex: number,
3  columnIndex: number,
4  columnData: array, // Columns Options object
5  rowData: array, // Full row data
6  tableData: array, // Full table data - Please use currentTableData instead
7  currentTableData: array, // The current table data
8  tableState: {
9    announceText: null|string,

16    },
17    showResponsive: boolean,
18    searchText: null|string,
19  },
20}, updateValue: function)

Plug-ins

The table lends itself to plug-ins in many areas, especially in the customRender functions. Many use cases for these render functions are common, so a set of plug-ins are available that you can use.

Available Plug-ins:

Name	Type	Default	Description
debounceSearchRender	function		Function that returns a function for the customSearchRender method. This plug-in allows you to create a debounced search which can be useful for server-side tables and tables with large data sets. function(debounceWait) => function Example

Customize Styling

Using Material-UI theme overrides will allow you to customize styling to your liking. First, determine which component you would want to target and then lookup the override classname. Let's start with a simple example where we will change the background color of a body cell to be red:

1import React from "react";
2import MUIDataTable from "mui-datatables";
3import { createTheme, ThemeProvider } from '@mui/material/styles';
4
5class BodyCellExample extends React.Component {
6
7  getMuiTheme = () => createTheme({
8    components: {
9      MUIDataTableBodyCell: {
10        styleOverrides:{
11          root: {
12              backgroundColor: "#FF0000"
13          }
14        }
15      }
16    }
17  })
18
19  render() {
20
21    return (
22		  <ThemeProvider theme={this.getMuiTheme()}>
23			  <MUIDataTable title={"ACME Employee list"} data={data} columns={columns} options={options} />
24		  </ThemeProvider>
25    );
26
27  }
28}
29

Custom Components

You can pass custom components to further customize the table:

1import React from "react";
2import Chip from '@mui/material/Chip';
3import MUIDataTable, { TableFilterList } from "mui-datatables";
4
5const CustomChip = ({ label, onDelete }) => {
6    return (
7        <Chip
8            variant="outlined"
9            color="secondary"
10            label={label}
11            onDelete={onDelete}
12        />
13    );
14};
15
16const CustomFilterList = (props) => {
17    return <TableFilterList {...props} ItemComponent={CustomChip} />;
18};
19
20class CustomDataTable extends React.Component {
21    render() {
22        return (
23            <MUIDataTable
24                columns={columns}
25                data={data}
26                components={{
27                  TableFilterList: CustomFilterList,
28                }}
29            />
30        );
31    }
32}

Supported customizable components:

• Checkbox - A special 'data-description' prop lets you differentiate checkboxes Example. Valid values: ['row-select', 'row-select-header', 'table-filter', 'table-view-col'].The dataIndex is also passed via the "data-index" prop.
• ExpandButton Example
• DragDropBackend
• TableBody
• TableViewCol - The component that displays the view/hide list of columns on the toolbar.
• TableFilterList - You can pass ItemComponent prop to render custom filter list item.
• TableFooter
• TableHead
• TableResize
• TableToolbar
• TableToolbarSelect
• Tooltip
• icons - An object containing optional replacement icon classes for the actions toolbar. Example
  • SearchIcon
  • DownloadIcon
  • PrintIcon
  • ViewColumnIcon
  • FilterIcon

For more information, please see this example. Additionally, all examples can be viewed live at our CodeSandbox.

Remote Data

If you are looking to work with remote data sets or handle pagination, filtering, and sorting on a remote server you can do that with the following options:

1const options = {
2  serverSide: true,
3  onTableChange: (action, tableState) => {
4    this.xhrRequest('my.api.com/tableData', result => {
5      this.setState({ data: result });
6    });
7  }
8};

Localization

This package decided that the cost of bringing in another library to perform localizations would be too expensive. Instead the ability to override all text labels (which aren't many) is offered through the options property textLabels. The available strings:

1const options = {
2  ...
3  textLabels: {
4    body: {
5      noMatch: "Sorry, no matching records found",
6      toolTip: "Sort",
7      columnHeaderTooltip: column => `Sort for ${column.label}`
8    },
9    pagination: {
10      next: "Next Page",
11      previous: "Previous Page",
12      rowsPerPage: "Rows per page:",
13      displayRows: "of",
14    },
15    toolbar: {
16      search: "Search",
17      downloadCsv: "Download CSV",
18      print: "Print",
19      viewColumns: "View Columns",
20      filterTable: "Filter Table",
21    },
22    filter: {
23      all: "All",
24      title: "FILTERS",
25      reset: "RESET",
