Axolot Data

Dear programmer colleagues!

I don't know if you decide to note the following lines as a bug or as an customer "wish for feature".
The problem is that the TXLSWorksheet.AutoWidthCol does not check if the cells in the column have a "foWrapText" option or not!.

The result the for the FColumns[ACol].PixelWidth must be smaller for a wraped celltext!

wraped text in excel cell
=====================
'Hello this is my wish
for the next update!'

the width will be wrongly calculated for :
==================================
'Hello this is my wish#10for the next update!'


To get the correct maximal ColWidth you can change your routines as follows:
The patched lines are marked!

It would be very nice if this could be included in the next update!
