Hi Swellerb,
Thanks for your interest in Essential XlsIO.
Issue 1: (Is it possible to generate an excel spreadsheet with fixed rows and columns)
--------
In Excel, every workbook has 256 columns and 65,526 rows. These values are fixed and cannot be changed.
Issue 2: (headers that don't move when you scroll down and also have the first few columns fixed)
--------
You can achieve this by using FreezePane property. Here is the code snippet to achieve this:
/Applying freezing pane in the sheet by specifying a cell
sheet.Range["B2"].FreezePanes();
Here is the sample for your reference:
