The column displays information from a bound data source, and you can edit the values of column to update the task details through TreeGrid. The operations such as sorting, filtering, and searching can be performed based on column definitions. To display a Gantt column, the field property should be mapped from the data source to the column.
If the column
fieldis not specified in the data source, the column values will be empty.
The treeColumnIndex property is used to define the expander column in the Gantt component to expand and collapse the child rows.
Using the columns property, you can define the columns in Gantt. If the columns are not defined, then the default columns will be rendered based on the mapped data source fields in the taskFields property. Refer to the following code example for defining the columns in Gantt along with their widths.

en-USculture.
The number or integer values can be formatted using the following format strings.
| Format | Description |
|---|---|
| N | Denotes numeric type. |
| C | Denotes currency type. |
| P | Denotes percentage type |
You can format date values either using the built-in date format string or a custom format string.
For the built-in date format, you can specify the columns.format property as string (example: yMd).
You can also use the custom format string to format the date values. Some of the custom formats and the formatted date values are given in the following table.
| Format | Formatted value |
|---|---|
| { type:‘date’, format:‘dd/MM/yyyy’ } | 04/07/2019 |
| { type:‘date’, format:‘dd.MM.yyyy’ } | 04.07.2019 |

</html>The column width can be resized by clicking and dragging the right edge of the column header. While dragging, the width of the column will be resized immediately. Each column can be auto resized by double-clicking the right edge of the column header to fit the width of that column based on the widest cell content. To resize the column, set the allowResizing property to true. The following code example shows how to enable the column resize feature in the Gantt component.
To resize the column, inject the Resize module into the Gantt component.

columns.allowResizingtofalse.
The column resizing can be restricted between minimum and maximum widths by defining the columns->minWidth and columns->maxWidth properties.
In the following example, the minimum and maximum widths are defined for the Duration, and Task Name columns.

The default items are displayed in the following table:
| Item | Description |
|---|---|
SortAscending |
Sort the current column in ascending order. |
SortDescending |
Sort the current column in descending order. |

You can define the tree column index in the Gantt component by using the treeColumnIndex property and the default value of this property is 0.

</html>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:
If the
typeis not defined, it will be determined from the first record of thedataSource. In case if the first record of thedataSourceis null/blank value for a column then it is necessary to define thetypefor that column.
The gantt has option to span the adjacent cells. You need to define the colSpan attribute to span cells in the QueryCellInfo event. In the following demo, Work 1 cells have been spanned.
