I’ve got a couple of table rows in a table layout. The last row got a button which I would like to stretch out to right side (i.e. fill the remaining space on right side in the row). When I try to stretch this button, other buttons in the row above also get stretched, which I don’t want to happen. See image link for what I’m trying to achieve. The green button is supposed to go over “three columns”.
Any tip on how I can do this?
