Table structure to fill in the blanks

Many of our users have requested a task type, that would enable them to create a table where students need to fill in the correct information to each cell. Basically this could be easily achieved by allowing to create a table structure in Fill in the blanks -question type text field. The end result that I am looking for is something like this (sorry for finnish texts, but I think this is pretty self explanatory):



This example is made by creating a fill in the blanks task and then a few line elements on top of it to make it look like a table.
