You simply specify the table as they should be, e.g. the column in
table B but not in A, and you set alterDatabase to true in the
writeSchemaToDatabase subtask.

However, please note that this will drop the data in the column in
table A. If there is a correspondence between rows in table A and
table B, and you want to move the data as well, you need to export the
data first to XML. Then use e.g. a XSL stylesheet to change the data
file so that the column with the data is in table B in the resulting
XML. And then after altering you reimport that data.
