IncludeInDataSet ft. Array

I guys, I've one question for you. I'm upgrading a matrix form.
The number of columns depends on the number of records inserted in a custom table.
To manage this I created 2 arrays, one that contains captions for the columns and the other one that contains the values that will printed in the repeater. This works as a charm.
my problem is that I never use all elements of the arrays and the columns that correspond to unused array's elements must disappear.
To do this I create another array of boolean values in which I specify if the columns must be printed or not.
But here I'm blocked because system says me that I can't set the property IncludeinDataSet to yes if Dimension <> 0.
the only idea I have is to create one boolean variable for each columns... but I really don't like it...
Does anyone of you have a suggestion?

Many Thx..
