How to set Text Format of Table column to allow % sign

[rsen]

I have added 5 columns to an ITable in a PPTX.

Now I want last 2 columns to have Percentage sign.

How can I set NumberFormat for column in ITable Shape ?

I have tried TextFrame.Format however this is Read-Only property.

table[i, 0].TextFrame.TextRange.Format = "F2"; //Error that Format is Read-only.

I fixed this by appending "%" character to the Column Values.

As far as I'm aware, the Powerpoint table , unlike ASP.NET / DataGridView has no formatting options other than Text align , margin,etc.
