44. Make a table view “responsive”
mmoodduullee:: ttaabbllee ttrraasshh
While we cannot make a table view truly
responsive, this does the next best thing.
When the table view is displayed on a tablet or a
phone, table trash hides the required number of
columns so that the report will fit on the device.
To expand the report the user can then click on
the plus next to the line in which they are
interested.
