Transforming the borders of the table in characters. Word COM server.

Good day everyone)
There is a task of transforming borders of the table with the data in the text with the characters "+" "|" "-" (instead of the borders) means a Word COM server automatation. Can someone tell me how to do it. Maybe it is already implemented in a Word or other programs?
Example (was a regular table in a Word document):

... and here was this:

it was the object table in a document, and became plain text instead of table borders.
I`m working with MVS C++.
Waiting for your thoughts. Thanks in advance)
