Column type

Column type can be specified using the columns.type property. It specifies the type of data the column binds.

If the format is defined for a column, the column uses type to select the appropriate format option number or date.

Gantt column supports the following types:

  • string
  • number
  • boolean
  • date
  • date time

If the type is not defined, it will be determined from the first record of the dataSource. In case if the first record of the dataSource is null/blank value for a column then it is necessary to define the type for that column.
