Hide Table Column When Visible Text is Blank

[bbergstrom]

Trying to use the Show Column If property but I'm running into an issue.  I'm trying to hide the column only if the text string is empty.  Trying to use the following where the field name is VehUdefName07:

VehUdefName07<>''

This appears to be scanning the entire data set as I filtered on a subset of data where this field is always empty but the column still appears.  Is there a trick to using this feature?

Try this:

Show column if
len(VehUdefName07) > 0

That is hiding the column even if there is data in some of the rows.
