# Welcome to the Highcharts Gantt JS (gantt) Options Reference

# dataTable

Options for one or many chart-level data tables. The `dataTable` option, or its array members, can be either configuration objects or instances of the `DataTable` class. If a `DataTable` instance is passed, it will be used directly. If a configuration object is passed, a new `DataTable` instance will be created based on the provided configuration.

The data table is mapped to the series data points based on the series.dataMapping option, unless the column keys match the point property names (`x`, `y` etc.), in which case the mapping is automatic.
