This one is a performance boost for cases where docs have lots of paragraphs inserted (through tables or whatever)... 

In the case that I found the issue, I was creating a report that added a lot of plain text paragraphs followed by lots of tables.. (creating a 40 page doc)

(the fix is to avoid using the Paragraphs collection to get the one that was just added.. it fixes the reference to the "mainPart" so things like images that are added still work... )

All unit tests pass after this test (did have to fix some case issues with the one that does text replacements though)

Includes:
-fix for default column widths (also works when column widths are not specified) - issue that was breaking tables with more than 14 cols
-New table method to set the widths for variable row tables... you can call Table.SetWidths(float [] yourWidthsInPixels) then for each row added those cols will have that width applied.. can help clean up some code.. also caches the column count for performance.. 

- Change for DocX that turns on zip compression for the parts of the doc (created docs are as small as re-saved versions from word now)
