This is probably a stupid question, but I'm still fairly new to Lyx. I want to use a longtable in my thesis. From what I've read across various sources, I need to rightclick on the table, click through to the "options => long tables" setting and then tick off the little box saying "use longtable". But for some reason I cannot tick it, it's greyed out so un-selectable. (Screenshot: http://i2.photobucket.com/albums/y8/lastalda/longtable.png)
Do I need to use some specific package to be able to access the longtable option? Or some special setting? (I'm using the koma(book) class, if that is relevant.) Thank you in advance for your help! Lastalda
