When I insert a new table in Safari 5, the cells are automatically populated with the word 'cell'.

 

On safari, if in tag <td> not content, it will display very small. It will lead to table that can not be edited, so we add the default text for the <td> tag.

 

2nd issue:

When I change the border properties of a cell (eg border 4px solid Green), this is reflected in the editor. But when I click away from the cell, the changes are removed.

 

Try click the "visible borders" button and then change the border.

 

Regards,
