i can figure out how to zoom the table/tombstone display on my PC Nomad. with the mouse you click and roll the wheel. but with just the trackpad, not sure. click/scroll doesnt work. for a minute i got pinching on the trackpad to work, but couldnt repeat it. any clue??
In the left-down corner of the tab you see a small gear-icon. If you press this there is a drop-down (more drop-up) menu and you can use Zoom-In and Zoom-Out.
Its funny because i came here because i couldn't find it myself, but after i read your question i got this idea and it worked. Goodluck!
