<?tbrulefc>
Description
With this command set, table-columns on the left of frame-columns will return true for (?l) or [l] when specified as the conditions for cell rules and background colors. It works similarly for right hand edges and the (?r) or [r] conditions. The command is only relevant when used in conjunction with <?tbamode=1>.
Additionally, if you want to detect an actual left column then use an explicit test of (x=1) when defining the rules and backgrounds. Identifying real right hand columns requires knowing the number of columns in advance: for instance you will only be able to set (x=5) to detect the right hand column of a table if you know it contains 5 columns.
