Subject line should read : PDFPTableEvents and Canvasing
[rodney.williams]
1. Can someone provide code in either C# or Java ( I can usually translate into
vb.net) which simply fires a table event where I can iterate through each row
and column. My understanding is that table layout and canvassing is involved.
If we can build on the code I provided, I hope the code will be simple. I
provided a working CreatePDF but The PDF Event procedure is one I tried to
make work but couldn't. My goal is to get the x,y coordinates as well as the
text from the fields to create and other some other file types.

Yes, the calculations are done by the program and are placed in the PDF Table.
I can't find examples anywhere of continuous horizontal scroll as you would do
in Excel. This is not related to the first question.

>> In one report there are 50 columns of totals for each of their
>> stores which they can read by simply moving horizontal scroll bar to
> the last column in Excel.
>> Can I accomplish the same with Itext/sharp?
