Michael,
I think you have probably figured out the code by now. It pads the cell on the
right. The code may look a little odd, but it does work, since the resulting
Braille tables look correct.

Hello,
In fixing the issue where tables may not have all cells in a row
specified, I found some code I cannot work out the actual meaning, may
be someone could help me.
The code in question is in transcriber.c in function utd_doAlignColumns.
The code is:
for (k = bufPos - 1; k >= prevBufPos; k--)
rowBuf[k + prevCol] = translatedBuffer[k];
for (; k >= prevCol; k--)
rowBuf[k + prevCol] = ' ';
I understand the main purpose is to copy the translated text of a column
into the row buffer and pad the cell at the beginning with spaces, but I
do not understand why the index of rowBuf should be k + prevCol. Why
should the beginning of a cell always be at twice prevCol? Does this
code even work?
