CopyTables is a plugin for Google Chrome that lets you select and copy cells in online tables as if they were a spreadsheet.
Download and install CopyTables from the Chrome Plugins store (it's free)
Restart Chrome
Hold down the alt/option key on your keyboard and drag to highlight multiple cells in any table in WholeCell!
