Cache the rendered cells

Previously, each time it tried to render a table (to check its width), it both re-queried the filesystem and re-formatted the values into coloured strings.

These values are now calculated only once before the table is drawn, and are used repeatedly throughout.

Although it looks as though there's more `clone()`ing going on than before, it used to be recalculating things and storing them as vectors anyway, so the memory would still be used in any case.
