property Items.CellFormatLevel([Item as Variant], [ColIndex as Variant]) as String
Specifies the arrangement of the fields inside the cell.

TypeDescription
Item as Variant A long expression that indicates the item's handle.
ColIndex as Variant A long expression that indicates the cell's handle or the column's index, a string expression that indicates the column's caption or the column's key.
String A CRD string expression that indicates the layout of the cell. The Index elements in the CRD string indicates the index of the column being displayed.
By default, the CellFormatLevel property is empty. If the CellFormatLevel property is empty, the cell displays it's caption. Use the CellValue property to assign a value to a cell. If the CellFormatLevel property is not empty, it indicates the layout being displayed in the cell's area. For instance, the CellFormatLevel = "1/2" indicates that the cell's area is vertically divided such as the up part displays the caption of the cell in the first column, and the down part displays the caption of the cell in the second column. The height of the item is NOT changed, after calling the CellFormatLevel property. Use the ItemHeight property to specify the height of the item. Use the DefaultItemHeight property to specify the default height of the items before inserting them. Use the Def(exCellFormatLevel) property to specify the layout for all cells in the same column. For instance, you can have a specify layout for some cells using the Def(exCellFormatLevel) property ( by default it is applied to all cells in the column ), and for other cells you can use the CellFormatLevel property to specify different layouts, or to remove the default layout. Use the FormatLevel property to arrange the columns in the control's header bar.

For instance, this layout [dgl=1]""[b=0]:4,(4;""[b=4]/0/4;""[b=1]),""[b=0]:4 adds a 4 pixels- borders around any object its applies ( in this case all columns ), like in the following picture:
