Merge columns horizontally

[javaexp]

Hi,
I am new to Docx4J as well open xml. My task is to merge columns horizontally as shown in the first row of image attached to this post.

Till now I have found the following code which seems not to work.

docx-java-f6/creating-tables-t212.html

Also the following tutorial does tell how to merge columns vertically which works but I need horizontal merging:
