To enable wrapping in table cells need to change css
/ resources / * your theme * / * your theme *-all.css
The original fragment:
. x-grid-cell-inner {
overflow: hidden;
white-space: nowrap;
zoom: 1;
on:
. x-grid-cell-inner {
overflow: hidden;
zoom: 1;
After the changes you need to rebuild the project and all your tablets can wrap text in their cells according to the automatic selection of the row height.
