ALV Grid to hold sub headings

Question

Hi,
Can any one tell me  about the possibility to display sub headings for an ALV grid control i.e to have a group of columns under one column similar to the feature in excel?
Regards,
Sujatha

Please not there are a number of differences between the structure of
ALVtree fieldcatalogs and ALVgrid fieldcatalogs.
For example the field seltext_m is replace by scrtext_m in ALVtree.
