Working with table data
Data management tools are also available through the Navigation bar of Table Editor.
If necessary, you can group the data in grid by any of the columns. This operation is performed by dragging the column header to the gray "Group by" box area at the top. When grouping by a column is applied to the grid, all the rows are displayed as subnodes to the grouping row value. To reverse grouping, just drag the column header back.
