Make the Matrix Word Wrap affect all row headers, including the last column.

[ironryan77]

Currently the matrix word-wrap only affects all but the last row header. Please fix so that it also affects the last row header. Also, it only affects the data values, not the row headers themselves. So if the row header label is too long, it just cuts off instead of wrapping.
