Override Grouping

Usage

To override the grouping text within the group row, use the column.groupRender callback function. It returns the grouped string for each group row for the given column and expects a renderable react node.

Additionally, the options.showGroupingCount (boolean) can be used to display the amount of items that are grouped under each group.

import MaterialTable from "@material-table/core";

<MaterialTable
  // ... other props
  columns={[field: "test", renderGroup: () => "Test"]}
  options={{
    showGroupingCount: true,
  }}
/>;

      data={DEMO_DATA}
      columns={DEMO_COLS.map((col) => ({
        ...col,
        renderGroup: (value) => `Test ${value}`,
      }))}
      options={{
        // Enabling grouping
        grouping: true,
        // Show the child count in brackets
        showGroupingCount: true,
      }}
    />
  );
