Writing in a narrowish column in a table, spacebar does not work, i.e. hitting it does not add a space. One can add the spaces between the words after hitting enter but not before.
Spacebar seems to work unless the first word is so long that the column begins to widen itself. If the long word is not first, it will correctly move to the next row and then the problem occurs on that row.
We're writing in Finnish that have longish words so we bump to this pretty often. An example in English in the image: long first word causes the problem.
