Hi Katherine,
The table size will accommodate the symbols at plan size option if you also check off the "Space Between Plants" option, in the schedule options.
Schedule Options:

For the remarks, they will actually wrap automatically. It just so happens that your particular remark is just a little short of the max column width before the remark will wrap.
You can adjust the column width in your table schedule by editing the schedule block and adjusting the column width. At this time, though, manual column width adjustments will not carry through a schedule regen, so you'll have to re-adjust it if you regenerate the schedule again.
