[Fixed Data Table 2](https://schrodinger.github.io/fixed-data-table-2/) for React · ![CI status](https://github.com/schrodinger/fixed-data-table-2/actions/workflows/build-and-run-tests.yml/badge.svg) · [![npm version](https://badge.fury.io/js/fixed-data-table-2.svg)](https://www.npmjs.com/package/fixed-data-table-2)

====================================



#### Fixed-Data-Table-2 is a continuation of [facebook/fixed-data-table](https://github.com/facebook/fixed-data-table).  The original repo is no longer maintained and has many pull requests awaiting response.



FixedDataTable is a React component for building and presenting data in a flexible, powerful way. It supports standard table features, like headers, columns, rows, header groupings, and both fixed-position and scrolling columns.



The table was designed to handle thousands of rows of data without sacrificing performance. Scrolling smoothly is a first-class goal of FixedDataTable and it's architected in a way to allow for flexibility and extensibility.



Features of FixedDataTable:

* Fixed headers and footer

* Both fixed and scrollable columns

* Handling huge amounts of data

* Variable row heights (with adaptive scroll positions)

* Column resizing

* Performant scrolling

* Customizable styling

* Jumping to a row or column

* Controlled scroll API allows touch support



Things the FixedDataTable **doesn't** do:

* FixedDataTable does not provide a layout reflow mechanism or calculate content layout information such as width and height of the cell contents. The developer has to provide the layout information to the table instead.

* FixedDataTable does not handle sorting of data. Instead it allows the developer to supply data getters that can be sort-, filter-, or tail-loading-aware.

* FixedDataTable does not fetch the data (see above)



This version of FixedDataTable is maintained by Schrödinger, Inc. It is a forked version of Facebook’s FixedDataTable Repository available [here](https://github.com/facebook/fixed-data-table) available under the BSD License.

Getting started

---------------



Install `fixed-data-table-2` using npm.



```shell

npm install fixed-data-table-2

```

Add the default stylesheet `dist/fixed-data-table.css` using a link tag or import it with a CSS module.



Implementing a table involves three component types- ``,``, and ``.



`` contains configuration information for the entire table, like dimensions and row count.



```javascript



  const rows =[0,1,2];



  

```    



`` defines the way data is displayed for one column in the table, including all cell behavior for that column. Rather than manipulating each cell directly, pass a cell component as a prop to the column, and the column will render a cell for each index in the data array.



```javascript

    Col 1}

      cell={Column 1}

      width={2000}

    />

```

The cell components in a column will receive the current array index of your data as a prop (`this.props.rowIndex`). Use this to access the correct value for each cell.

```javascript

    const rows = [0,1,2];

    

    Column 1}

      cell={({rowIndex, ...props}) => (

        

        {rows[rowIndex]}

        

      )}

      width={2000}

    />

```



If your data is an array of objects, define a `columnKey` prop for each column and it too will be passed to all cells in that column.

```javascript

    const rows = [

      { someKey: "someValue" },

      { someKey: "anotherValue" },

      { someKey: "yetAnother" }

    ];

    

  Col 1}

    columnKey="someKey"

    cell={({ rowIndex, columnKey, ...props }) =>

      

        {rows[rowIndex][columnKey]}

      }

    width={2000}

  />;



```



You may find it useful to define custom Cell components, which can also be passed to the Column:

```javascript

    const MyCustomCell = ({ isSpecial }) =>

      

        {isSpecial ? "I'm Special" : "I'm Not Special"}

      ;



    Col 3}

      cell={}

      width={2000}

    />



```



### Code Sample

For more detailed examples, please see the [examples section](http://schrodinger.github.io/fixed-data-table-2/example-object-data.html) of the documentation. If you need help getting started with a React build system, we recommend [create-react-app](https://github.com/facebookincubator/create-react-app).  

```javascript

import React from 'react';

import ReactDOM from 'react-dom';

import {Table, Column, Cell} from 'fixed-data-table-2';

import 'fixed-data-table-2/dist/fixed-data-table.css';



// Table data as a list of array.

const rows = [

  "first row",

  "second row",

  "third row"

  // .... and more

];



// Custom cell implementation with special prop

const MyCustomCell = ({ mySpecialProp }) =>

  

    {mySpecialProp === "column2" ? "I'm column 2" : "I'm not column 2"}

  ;



// Render your table

ReactDOM.render(

  

    Col 1}

      cell={Column 1 static content}

      width={2000}

    />

    Col 2}

      cell={}

      width={1000}

    />

    Col 3}

      cell={({rowIndex, ...props}) => (

        

          Data for column 3: {rows[rowIndex]}

        

      )}

      width={2000}

    />

  ,

  document.getElementById('example')

);

```
