Hide 1 of 3 header row

Hi experts.

Maybe you can help me.

I have table:

Header

  -header_row_1

  -header_row_2

  -header_row_3

Body

Footer

On same pages i need to hide "header_row_1". Is it possible?.

I tried to do this:

data.Table.Table.Header.Table4.ActRow::ready:layout - (FormCalc, client)

var pg = xfa.layout.page( ref($) )

if ( pg == 1 or pg == 3 or pg == 5 or pg == 7 or pg == 9 or pg == 11 or pg == 13 ) then

  $.presence = "Visible"

else

  $.presence = "hidden"

endif

Almost its works. But a have FREE space then i hide row.
