You should be able to toggle visibility of the columns in the report
via an expression. Right-clicking the column in the table control and
selecting properties and select the tab for visibility and then enter
an expression that checks for the sum of the column's value. Something
like this should work:
=iif(Sum(Fields!ColumnItemX.Value) > 0, "true", "false")
Also, you might want to make sure that for individual cells, the
shrink to fit (or similar wording) is selected and that you
conditionally set border styles based on if the column is visible
(via, Properties -> Border Style: =iif(Sum(Fields!ColumnItemX.Value) >
0, "Solid", "None"))
Hope this helps.
