Specific cell data types can also be defined by setting the cellDataType property on the column definition. Value Getters are used in all subsequent columns as follows: Column '' prints the row number, taken from the Row Node. Moving columns from within the Columns Tool Panel has been disabled as suppressColumnMove is enabled. Moving columns in the grid won't affect the custom layouts as suppressSyncLayoutWithGrid is enabled. / An object map of custom column types which contain groups of properties that column definitions can inherit by referencing in their type property. These row groups will be displayed using Group Rows as groupDisplayType groupRows. These are enabled by default, with the data type being inferred from the row data if possible (see Inferring Data Types). Clicking Custom Group Layout invokes setColumnLayout(colDefs) with a list of column definitions containing groups that don't appear in the grid. To display each row group using group rows set groupDisplayType groupRows as shown below: In the snippet above, rows will be grouped by country and year as both column definitions have rowGrouptrue declared. There are six pre-defined cell data types: 'text', 'number', 'boolean', 'date', 'dateString' and 'object'. The Filter List will match the tree structure. Tree Data mode is enabled and the column is a group column. Note that if the Date objects have a time defined, then a Key Creator must also be supplied to generate a unique key without the time. If you’d like to change this behaviour and apply the filter only to specific group row levels, or specific grouped columns (regardless of the level at which these group columns appear), a callback can be provided to the groupAggFiltering. month -> day. As seen above, the default behaviour of Filtering Group Aggregations is to apply the filter to all row group levels. While column defs are just plain objects at the end of the day, a createColumnHelper function is exposed from the table core which, when called with a row type.

If both field and colId are missing, a unique ID will be generated. This allows different grid features to work without any additional configuration, including Rendering, Editing, Filtering, Sorting, Row Grouping and Import & Export ( CSV Export, Excel Export, Clipboard). If missing, the ID will default to the field. The Gold, Silver and Bronze value columns have different agg functions applied via with values of different data types is made easy by using cell data types. Rows are grouped by the Country and Year columns by enabling the rowGroup column definition property. The example below uses the same built-in aggregation functions shown in the snippet above. The following snippet shows how these agg functions can be applied to columns via colDef.aggFunc: const gridOptions = You can set colDef.enableValue=true to enable aggregation via the column menu and dragging in the columns tool panel.Īnother way to enable aggregations is with the built-in aggregation functions: sum, min, max, count, avg, first, and last. There are two ways to enable aggregation.

When Row Grouping, aggregation functions can be applied to any column to populate the group row with values.
