If I create a table in the web client, it is too wide to view on my phone. You are then stuck in that very awkward swiping right and left mode in an attempt to see everything.
Switch my phone to landscape? If only. Nope, still doesn't fit.
Attempt to modify table width on the web client? Doesn't seem to allow it - moving the margin right and left only changes the width of the last column.
Tables are good, let's fully support them!
