IE: we can't switch to to source mode when we insert a Table with caption or first row or both first row & column set as Table Headers

[Satya Minnekanti]

To reproduce the defect:

1. Open CK Editor and insert a Table with a caption.

2. click on Source button in Toolbar.

Expected Result:

we are in source mode and html for the inserted table is shown.

Actual Result:

Editor stays in WYSIWYG mode and it will shown an error and when we click on that error it says object doesn't support this property or method.

same behaviour happens when we insert a table with first row set as headers or both first row and first column set as headers
