<?blockcellrulelgut>

Used to make a rule that is assigned to a cell span into the gutter to the left of that cell. If the command is entered at the top of the block it will apply to every cell in the block: it is, however, possible to override it with individual cell commands.

[no parameter]

code

0	Do not span rules into gutter.
1, f, F, l, or L	Full or left: span rules over the whole of the left gutter, including those drawn via the <?blockgutl> command.
2, c, C, m, M, h or H	Center, mid or half: span rules half way into the left gutter, including those drawn via the <?blockgutl> command.
3, s or S	Special: span rules halfway into normal left gutters, but all the way into a left gutter drawn via the <?blockgutl> command. This assumes that the left hand gutter is half the width of gutters in the body of the table and will provide an even effect.
