How to hide columns in rtf

@column

Hi Gurus,I am facing issue while hiding table in rtf template.

I have a table where there six sections are available. But my data will not be available through out for six sections. I need to hide columns and give the space back to rest columns.

Here my table structure is like below

six section like this in each box

1         4

2         5

3         6

For suppose if  1 and 3 are present and 2 is not, then section3 would show where 2 would usually go.

I have tried using @column but problem is that i am using same group in six different sections, as this has also child section for each group that why repeating it for six times.
