The grid appends '_1' to Col 4 to make the ID unique. The grid appends '_1' to Col 2 to make the ID unique.

Open the example in a new tab and observe the output in the dev console. In the example below, columns are set up to demonstrate the different ways IDs are generated. However, some types require additional properties to be. Finally, the ID is ensured to be unique by appending '_n' if necessary, where n is the first positive number that allows uniqueness. To use most of the column types, you only need to define the type property in your column definition. If neither colId nor field exists then a number is assigned. To specify a set of columns to be created in a grid, assign an array specifying these. If both colId and field exist then colId gets preference. By default, a column is created for each field of a data source object, but in most cases, it is redundant. If the user provides colId in the column definition, then this is used, otherwise the field is used. if two columns have the same field, or if you are using valueGetter instead of field) then it is useful to understand how column IDs are generated. If you are using the API and the column IDs are a little complex (e.g. As for Borders, a Grid only contains the ShowGridLines property, which can be used to show thin dotted. Or if you want it set for individual cells, you need to add an element to the cell that has its Background property set.

The following example shows a simple grid with 3 columns defined: const gridOptions = Column IDsĮach column generated by the grid is given a unique Column ID, which is used in parts of the Grid API. Each column generated by the grid is given a unique Column ID, which is used in parts of the Grid API. The Background color can just be set for the entire Grid by using the Background property: .

Columns are positioned in the grid according to the order the Column Definitions are specified in the Grid Options. Each column in the grid is defined using a Column Definition ( ColDef).
