Issue with adding more than 36 columns to a table

If I enter 37 or more columns to a table, any text I set in cells are ignored and the leftmost part of the table is not where I asked it to be.

If I enter 36 or less columns to a table, I do not get this issue.

I generated a sample project with this error that I will upload upon request.


Dear Jeff,

Yes, please upload it, it will be helpful to look into this problem.

The web project is attached. It asks for the number of columns to generate and saves the result as c:\sample.ppt.

Notice that the results are as expected if there are 36 or less, but not when there are 37 or more.

Hello Jeff,

You use too large column width.
MS PowerPoint stores all shape coordinates as signed 16-bit integer so it can’t be more than 32767.
But you try to set table width equal to 900*37=33300 or more.
