I've never used the module, but the documentation seems pretty straightforward. I can only imagine the ability to precisely position text if you use a table. Relevant snippets of the docs:

insertTable(element, name, rows, columns [, options])

        Creates a new table and inserts it immediately before or after
        another element (paragraph, header, table). The referenced ele
+ment
        can be indicated as in insertParagraph. The other arguments an
+d
        options are the same as for appendTable with the additional op
+tion
        'position' as in insertParagraph.

And then to set the contents of your cell:

updateCell(element, value [, text])

        Modifies the content of a table cell.

        In its first form, indicates a cell by its 3D coordinates, as 
+with
        getCell(). In its second form, indicates a cell by its element
        reference.

        If the cell is set to literal, its content is limited to its t
+ext.
        In this case, the optional argument "text" is of no use (the t
+ext
        equals the value).

        If the cell is set to numeric (float, currency, date, etc.), y
+ou
        should generally pass a literal argument as well as the value.

        This method can be replaced by the accessor cellValue which al
+lows
        reads and writes.
