As far as I know Ben,

It’s still not possible to conditionally hide/show a column in a table.

From what i read on other posts, they are working on this for a future release

For now the only workaround I know of, depending on case use, is either multiple tables as you mentioned or Merge Syntax { #field}} {{/field}} {{^field}} {{/field}}.

but second option only good for specific cases (if field not blank, show xyz, if blank, show ABC or nothing)

Thanks Dave. I took the multiple tables option and set the rendering conditions. Appreciate the reply - this would be a great feature to have in future releases, and I’m sure they have a million others they are working on.
