If we are really talking of a worksheet function (rather than Data > Table
as Peo Sjoblom has suggested) then it must be a user-defined function, so
you would have to refer to the author for details.
Peo is correct. TABLE (or any variation involving different case of any of its
letters) can't be used as a UDF name. Try it.
TABLE *appears* to be a function, but it is in fact Excel's mechanism for
implementing Data > Table. Since Excel provides automatic recalculation options
including and excluding tables (and always has), it seems (proof would require
reading Microsoft design specs for Excel, if there are any) that Microsoft used
something that looked like a worksheet function to do this. However, TABLE is
*NOT* a worksheet function in the sense that users may type it into formulas in
any range. *ONLY* the Data > Table menu command (or macro equivalents) can
'enter' it into ranges, and it's *ALL* that can appear in such 'formulas'.
