Add some extra columns!?

Hy, we use a older pswriteword module... but for developing... i search for an easy way to expand this example:

to insert some extra columns.

So with my understanding, each `$InvoiceEntry1` becomes a new row. But how can i define several values, to generate more cells in a row?
