Merge cells at runtime in Adobe Form

Question

Help.
I have 6 columns in  a table .
I need to write a script in adobe form to check the value of the 5th column
if  5th column = 'T' then I need merge 1th,2th,3th columns
If  5th column = ' ' then do nothing
I write JavaScript
data.#subform[0].TABLE.DATA::initialize
if ( this.COLUMN5.rawValue == "T" )
this.COLUMN1.colSpan = "3" ;
The cell's merged  but not correct. In the row with  column = 'T'   appear the new columns.

Well you are on right track. Just use the code in your first post and second post for complete solution.
I tried with a simple table with 1 row and below is the JavaScript code I used in the initialize event of Subform:-
Table1.Row1.Cell5.rawValue = "T";
if(Table1.Row1.Cell5.rawValue == "T")
     Table1.Row1.Cell1.colSpan = "3" ;
     Table1.Row1.Cell2.presence = "hidden";
     Table1.Row1.Cell3.presence = "hidden";
