Reproducing Procedures

1. Open 'replacebyclass' sample page insert an default table.
2. Click inside one of the table cell and open context menu on it.
3. Click 'Table Properties' to open the dialog.
4. Press 'Tab' key to iterate over all dialog fields.

• Actual Result: Some fields will be skipped before reach the dialog buttons.

1. the simplest way to fix this problem is not make a default focus, cos it disarranged the focus sequence. this is my chosen
   

2. an optional way may be rearrange the dialog's elements layout sequence, e.g. switch the 'selHeaders' select with 'txtWidth' input( and other element switch);
   

3. adjust the focusList by hand, I think this is not scalable .

pls neglect the first patch

I'm not sure this will be a good deal, as the smart focus is a friendly feature also exists in other places, e.g. Link dialog, where we have the same problem, we may even consider a wontfix for this one if no decent solution could be found.
