DOI Wordprocessor: why is long text being cut in table cells?

I use DOI Word Processor Interface to populate a [templ.doc] template file with data.

There is an empty table in the template and I put there my internal table content with

the method wpi->insert_table2( ).

The problem long (too long for corresponding cells) strings are not wrapped but cut to the length of the cells.

As a result I have loss of data.

Also tried wpi->insert_table() but the same result.

How do I solve the problem?
