Making a repeating table header line cells invisible




I have a table that spans over several pages, with a header line that repeats in all of them.

I need to set some of the header line's cells to be invisible.

I did Table.Header.Cell1.visible = "invisible", but that only affects the first occurence of the header line, and the ones on other pages are not affected.

How can I make all the header lines cells invisible?

I tried Table.Header.instanceManager, but it only has one instance.

I've also tried Table.nodes, but again, the header line appears there only once. I need to access these lines with code somehow.

Thanks, Arik.
