[AccessD] Excel Question

[Arthur Fuller]

I am creating an Excel workbook from VBA code. I need to know this: Is
there a maximum number of sheets in a Workbook?
I also need to know if there is a way to programmatically set the
column-widths (equivalent to moving the cursor to the right edge of a
column then double-clicking).

And finally, how can I set row 1 (containing the headers to Bold?
