I'm sorry for the inconvenience. There are some bugs reported on the macro. The bug-fix will be done as soon as the solution is found.
The macro can't deal with merged cells on the row A or the column 1. From the cells in the bellow figure, for example, you can't get the correct result.
The problem comes from the way of checking if a cells are merged or not.
To avoid this problem, please make a table away from the edges. (If any cells are not on the row A or the column 1, you don't have to follow this solution.)
I'm sorry for the inconvenience and the trouble this causes you.
This bug has been fixed in version 0.2.4. (October 29, 2005)
