Is it possible to make a ColumnSpan in the Fields of a Sub Table of Table.

Table:        Text                                                      Total                Value1    Value2

SubTable:  Very long text that goes into this the total value      Value1    Value 2

In the SubTable the first field has a colspan = 2;

Thanks in advance

P.S.: I now I can achieve this with a group but then I have to align manually the fields.
