RightToLeft property not working in the Table class

I’m trying to use the “RightToLeft” property to set the Table’s reading direction to “Right To Left”. However, it doesn’t seem to work. Please see my complete code below and I’m using the latest version of the Slides dll (16.12). I attached two files. One is called “Aspose_Generated_RTL” which is the pptx generated by the code below. The other attached file named “Expected_RTL” which is a version that we modified to demonstrate how the table should look like in a RTL language. If you can take a look at the code and compare those two attached files, and let us know why the Tabel’s “RightToLeft” is not producing the expected result, we will really appreciate it.
