Hello Mohammed.

Thank you for your interest in our plugin, and thanks for the kind words.

The RTL support is planned, although I cannot say when it will be implemented.

There is a workaround, though.

You can add a class to each column you want to be RTL - something like "rtl". 

And then add the following CSS in Custom CSS field under main settings of wpDataTables:

table.wpDataTable td.rtl {
    unicode-bidi: bidi-override;
}

This should override the settings and make the column display RTL.

Best regards.
