Columns in Vue TreeGrid component

29 Sep 2022 / 19 minutes to read

The column definitions are used as the dataSource schema in the TreeGrid. This plays a vital role in rendering column values in the required format. The treegrid operations such as sorting, filtering and searching etc. are performed based on column definitions. The field property of the columns is necessary to map the data source values in TreeGrid columns.

If the column field is not specified in the dataSource, the column values will be empty.

If the field name contains “dot” operator, it is considered as complex binding.

treeColumnIndex property denotes the column that is used to expand and collapse child rows.

Header Template

You can customize the header element by using the headerTemplate property.

If both the field and headerText are not defined in the column, the column renders with “empty” header text.

Format

To format cell values based on specific culture, use the columns.format property. The TreeGrid uses Internalization library to format number and date values.
