Issue Summary

When creating Word tables using python-docx, setting paragraphs or runs to right-to-left (RTL) alignment works inside the cells. However, the table itself remains left-to-right (LTR) in layout.

This means the column order is reversed, and the first column (e.g., row number) appears on the left instead of the right. This is problematic for documents in RTL languages like Persian, Arabic, or Hebrew.

Steps to Reproduce

1. Create a table with doc.add_table(rows=1, cols=3)
2. Set paragraph alignment and bidi/textDirection to RTL
3. Save the document
4. Open the .docx in Word — the table layout remains LTR.

Expected Behavior

The table should support RTL direction fully, where:

• Columns flow from right to left.
