Data Table

A Data Table is a structured representation of data, consisting of columns and rows. It offers methods for adding, removing, and manipulating columns and rows, as well as for accessing data from specific cells.
Think of a Data Table as a grid where each row represents a record or entry, and each column represents a specific attribute or piece of information.

Creating a DataTable

There are a few ways to create a DataTable:

  1. From a DataPool
    The DataPool is the main entry point for data handling in Highcharts Dashboards. It handles incoming data and creates a DataTable to store the imported data.

    It can be created automatically when you create a Dashboard:

    Dashboards.board('container', {
    dataPool: {
    connectors: [{
    type: 'CSV',
    id: 'my-connector',
    options: {
    csvURL: ''c

    Or you can create it manually with connector options:

    const dataPool = new DataPool();
    type: 'CSV',
    id: 'my-connector',
    options: {
    csvURL: ''
    const dataTable = await dataPool.getConnectorTable('my-connector');
  1. From a DataConnector
    A DataConnector is a service that retrieves data from an external source and creates a DataTable to store the imported data.
    The DataTable is accessible via the DataConnector.table

    async function loadData() {
    const connector = new DataConnector.types.CSV({
    csvURL: ''
    await connector.load();
    const dataTable = connector.table;
  2. Manually
    You can create a DataTable manually by providing the columns and rows.

    const dataTable = new DataTable({
    columns: {
    x: [1, 2, 3, 4, 5, 6],
    y: ['a', 'a', 'b', 'b', 'c', 'c']
  3. From a DataModifier
    A DataModifier is a service that modifies data in a DataTable. It can create a new DataTable with the modified data.

    const sortModifier = new DataModifier.types.Sort({
    direction: 'asc',
    orderByColumn: 'City'
    const table = new Highcharts.DataTable({
    columns: {
    Rank: [1, 2, 3, 4, 5, 6],
    City: ['Sydney', 'Melbourne', 'Brisbane', 'Perth', 'Adelaide', 'Canberra'],
    State: ['NSW', 'VIC', 'QLD', 'WA', 'SA', 'ACT'],
    Population: [5259764, 4976157, 2568927, 2192229, 1402393, 453558]
    const tableModified = sortModifier.modifyTable(table.clone());

Get operations

A DataTable offers several methods to access data, among some of the most common are:

  • getRow- Returns a row with the specified index from the DataTable.
  • getRows- Returns all or a number of rows.
  • getRowIndexBy- Returns the index of the first row that matches the specified condition.
  • getColumn- Returns a column with the specified name or alias from the DataTable.
  • getColumns- Returns all or a number of columns.
  • getModifier- Returns the modifier for the table.

And many more. For a full list of methods, see the API documentation.

Set operations

A DataTable offers several methods to modify data, among some of the most common are:

  • setRow- Sets cell values of a row.
  • setRows- Sets cell values of multiple rows.
  • setColumn- Sets cell values for a column.
  • setColumns- Sets cell values for multiple columns.
  • setModifier- Sets or unsets the modifier for the table.

See other available methods in the API documentation.

Other operations

Other useful operations include:

  • clone- Returns a clone of the table.
  • deleteColumns- Deletes columns from the table.
  • deleteRows- Deletes rows from the table.
  • on- Adds an event listener to the table for a specific event.
