Financial Underlining
 

Does anyone know if their is a way of doing what I call financial overlining
and underlining in a set of accounts. What I ideally would like is a
single overline and a double underline in selected cells which extends to
the length of the number in that cell. The only way I can do it is to draw
lines in the cell but that has the disadvantage of not being very portable
and the accounts need much tweeking to get these all looking the same and
being the same sizes and alignment through the document. Cell borders
nearly does the trick but are too wide if the column is set up to hold the
column descriptions.
