Hi all,

I have a 2-dimensional table with 234 columns and 604 rows. Column headings
are A011100, A011200, ... E425100, E425900; row headings are 11111, 11112,
.... 91513, 91514. (In case you're interested, column headings represent
industries, row headings represent occupations, and table data is of
employment).

I want to be able to condense this table on the basis of the leading
characters of the row and column headings. In other words, I'd like to end
up with a table with, for example, column headings A, B,...E and row
headings 11, 12, ...84, 91; in this aggregated table, cell 11A would
contain the sum of all values in cells from the original table with column
headings A011100 - A011990 and row headings 11111 - 11411 (and so on for
cells B11-E91).

Can anybody point me in the right direction?

Thanks in advance,
Mark
