You do mean the widget ‘Table’? If so, this is not possible in the table itself, it just does not have the visibility-option like it has for rows:
You can duplicate the table, one with the column visible, one having the column not visible. Wrap both of them in a dataview. Make the dataview have as datasource an entity containing your boolean. And on both your tables set the visibility based on that value of the boolean-attribute.
I think, In the Select Attribute dialog box, select an attribute of the Boolean or enumeration type and click Select.
