The icon is very simple looking and is shaped like a very thin rectangle shape. Each corner of the rectangle shape is pointed. The shape is laying flat in a horizontal position.
Mahop, definitely. However, we have 6 icons per request rule (and get stuck to it for couple years), so you may want to create a new idea. Thank you for generating great ideas!

Would be great including table Operations like Insert Row / Col, Delete Row / Col, Insert Cell / Delete Cell...
