Misreading of merged header cells in Word

[andrew-l-d]

Using nvda_snapshot_master-13477,dc3ad4ce to read merged cells in a Word table the second column in the body is associated with the second heading, which covers columns 3 and 4. The attached file demonstrates this; mamels are associated with land-dwelling rather than sea-dwelling. Nevertheless, a big step forward with Word tables.

Trying to better describe the issue:
The issue is that the first header spans columns 1 and 2, while the second header spans columns 3 and 4. However, both headers count as 1 column. So on the next row the second column, with number 2, is reported as falling under the second header, that should have number 3 but instead got number 2.

I am interested in working on this, but will first have to study the relevant code.

This is fixed in the UIA implementation, but should also be done for Word 2010 and 2013.
