if we want to use `\t` to separate columns, it’s not possible to create an empty cell the way it’s currently setup. From memory I would say that this is currently not the case. For now put something like `if(row.match(/\t\t/)) { window.debug.printStackTrace(); throw('multi tabs'); }` in, so you can catch places where  multiple tabs are used erroneously. Once that’s fixed it can be removed and we gain empty table cells.
