If several rows or columns have the same header, rows and columns can be combined using the Add Group Columns aggregation and a hierarchy can be created. There are two ways of doing this:
Group columns (TableColumnGroup)
Table columns (TableColumn)
For this purpose, the first three header lines are highlighted in color.
You can find an example in the system in the WDR_TEST_TABLE component.
