How to generate table column head in Arbortext Styler with condition?

Hi Experts,

I am new to using Arbortext Styler, and using FOSI for output, How to generate Table Column Head by condition based?

for example:

<tbl><row><effect effrg="001999"></effect><cb cbtype="elmec">5-PB-2</cb>

<cbname>ELEC/HOT BUS/702PP SPLY</cbname><pan pantype="elec"> 105VU</pan>

<cbloc>D02</cbloc></row>

<row><effect effrg="001999"></effect><cb cbtype="elmec">5-PB-2</cb>

<cbname>ELEC/HOT BUS/702PP SPLY</cbname><pan pantype="elec"> 105VU</pan>

<cbloc>D02</cbloc></row></tbl>

I want generate heading like "effective number" for element of effect, "cb number" for element of cb, same like all the cells.....

Note: Cell element is optional in the "cbdata", if "cb" is there, then need to show "cb number" in table column heading, if not, no need to show the "cb number".......(for all the cells need to show like with condition).

Please any one guide me, Thanks in advance!

Cheers,

SARAN
