This is an enhancement request from Novell bugzilla, in which community may be interested:

There are two basic ways to make the text in a cell vertical:

1) Select all the text in a cell and set turning angle in the character
properties to 90 or 270 degrees
This method has a severe drawback: the text gets messed up if it does not fit
into a cell with height explicitly set, and the cell height becomes locked once
a non-fitting text is entered (or pasted) there - instead of word-wrapping the
text, the cell just does not resize. Moreover, text fitting rules seem to be
different from those of the cells with horizontally oriented characters - the
cell requires more height (for text it is width) to fit the text properly than
it would if the text was horizontal. It all makes text editing terribly
inconvenient in that case.

2) Set text direction in the table properties (right-click inside the cell,
Table...->Text Flow->Text Direction->Right-to-left (vertical))
This one works much better in that case, but unfortunately it's required
sometimes that the text is bottom-to-top and left-to-right.

Summarizing all this, can I suggest adding a "Left-to-right (vertical)" text
direction in the Table Properties dialog, Text Flow tab?

(Also, is the rotated text behavior described above a bug? If it is, I will
file it properly.)
