Introduction to Fixed Data Table

The Fixed Data Table is a highly performant table view for rendering large datasets. Its architecture allows developers to handle large amounts of data with smooth scrolling and high rendering performance. Developed and maintained by Facebook, the Fixed Data Table addresses many common issues faced when developing table views. This guide aims to provide an in-depth introduction to its functionalities, features, and some of the most useful APIs, complete with code snippets and examples.

Getting Started

First, you need to install the Fixed Data Table package:

  
  npm install fixed-data-table-2
  

Next, import the necessary components in your project:

  
  import { Table, Column, Cell } from 'fixed-data-table-2';
  import 'fixed-data-table-2/dist/fixed-data-table.css';
  

Setting Up Your First Table

Below is an example of how to set up a basic table:

  
  const MyTable = ({ data }) => (
    <Table
      rowHeight={50}
      headerHeight={50}
      rowsCount={data.length}
      width={1000}
      height={500}>
      <Column
        header=<Cell>Name</Cell>
        cell={({ rowIndex }) => (
          <Cell>{data[rowIndex].name}</Cell>
        )}
        width={200}
      />
      <Column
        header=<Cell>Age</Cell>
        cell={({ rowIndex }) => (
          <Cell>{data[rowIndex].age}</Cell>
        )}
        width={100}
      />
      <Column
        header=<Cell>Address</Cell>
        cell={({ rowIndex }) => (
          <Cell>{data[rowIndex].address}</Cell>
        )}
        width={700}
      />
    </Table>
  );
  

Key API Features with Examples

Resizable Columns

  
  <Column
    header=<Cell>Resizable</Cell>
    cell={({ rowIndex }) => (
      <Cell>{data[rowIndex].resizable}</Cell>
    )}
    width={200}
    isResizable={true}
  />
  

Column Groups

  
  <ColumnGroup
    header=<Cell>Group 1</Cell>>
    <Column
      header=<Cell>Sub-column 1</Cell>
      cell={({ rowIndex }) => (
        <Cell>{data[rowIndex].subcolumn1}</Cell>
      )}
      width={200}
    />
    <Column
      header=<Cell>Sub-column 2</Cell>
      cell={({ rowIndex }) => (
        <Cell>{data[rowIndex].subcolumn2}</Cell>
      )}
      width={200}
    />
  </ColumnGroup>
  

Sortable Columns

  
  <Column
    header={
      <SortHeaderCell
        onSortChange={(columnKey, sortDir) => {
          // Sorting functionality
          this.setState({
            sortedData: sortData(data, columnKey, sortDir),
          });
        }}
      >Sortable</SortHeaderCell>
    }
    cell={({ rowIndex }) => (
      <Cell>{data[rowIndex].sortable}</Cell>
    )}
    width={200}
  />
  

Complete Example with Multiple Features

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

  const data = [/* your data here */];

  class App extends Component {
    render() {
      return (
        <Table
          rowHeight={50}
          headerHeight={50}
          rowsCount={data.length}
          width={1000}
          height={500}>
          <Column
            header=<Cell>Name</Cell>
            cell={({ rowIndex }) => (
              <Cell>{data[rowIndex].name}</Cell>
            )}
            width={200}
            isResizable={true}
            isSortable={true}
          />
          <Column
            header=<Cell>Age</Cell>
            cell={({ rowIndex }) => (
              <Cell>{data[rowIndex].age}</Cell>
            )}
            width={100}
          />
          <Column
            header=<Cell>Address</Cell>
            cell={({ rowIndex }) => (
              <Cell>{data[rowIndex].address}</Cell>
            )}
            width={700}
            isSortable={true}
          />
        </Table>
      );
    }
  }

  export default App;
