When I create a menu in this way "Category -> Column Layout" it is supposed to display all the products in column. In config I have "Number of Columns in Column Layout = 2". Nonetheless, the number of columns remains as one column.
Alternatively, I thought I could use a table (Category -> Table Layout) but I don't see where the table rows and columns are configurable.
I have documents listed by table, and have set the number of columns in the Themes tab to "2".
Items appear in one column, and I also get a blank column.
If I set the number of columns to "3", I get two columns and a blank column.
The blank column takes up a third of the window, and makes the page look silly.
