If the cursor is not in the right-most cell, Guide Designer inserts the label at the current cursor position. The field is inserted into the cell to the right of the cursor. If the cell to the right has something in it, Guide Designer appends the field to this information.
If the cursor is in the right-most cell and the cell isn't empty, Guide Designer places the label and the field into the first two columns of the row that follows. If that row has text in it, Guide Designer inserts a row immediately beneath the current row, and then inserts the label and field. If that row is empty, just write place the information into the cell.
If the cursor is in an empty right-most cell or if the table has only one column, Guide Designer places the field (not the label) into this cell.
