Disable sortable for certain table cells and change sensitivity?

Disable sortable for certain table cells and change sensitivity?

Hey,

I'm using jQuery Sortable on a table and it works to re-arrange rows. One of the columns is a link and I don't want that column to be "draggable". Can I turn of the sorting for just that one column?

Also is it possible to reduce the sensitivity on the actual grabbing? I have another ul list where every li is a toggle button AND sortable. Sometimes I just want to click it, but it reacts so quick that it starts to drag it instead. I have to be really careful. Is there a parameter to change this sensitivity?

Thank you!
