Make a table view “responsive”

module: table trashmodule: table trash 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.
