Disabling table-handles in midas

Hi

I'm incorporating the midas editing component of mozilla in our CMS tool 
and would like to turn off those little handles you get when you've 
created a table (I mean those use can use to insert or remove 
rows/columns or to resize the table).

Anyone an idea on how to do this?

I'm just using the contentEditable=true flag in the editable pages, and 
controlling the whole thing via javascript.
