group_rows not working properly for latex tables

[JamesCuster]

I am having almost the exact same issue as reported in #254, but the fix that was applied does not seem to fix the problem for me. I recently installed the newest version of R and Rstudio and wondering if that might have something to do with the bug that I am seeing because it hadn't happened previously. The below reproduced the bug for me.

Yeah, I also realized this recently. The last fix didn't entirely fix the issue.There are several reported issue that are related to this. I will try to get it fixed in the next version.

Yea, I saw the other post, but I got the impression that those had been resolved. Thank you for the update though. Do you have a suggestion for a quick fix that I might be able to implement. The tables are for my thesis which I need to submit in a few weeks. If not, it is ok. For now I have just gone in and modified the raw LaTeX code which works fine, was just hoping to have an alternative to that.

Also, love the package by the way! I have been using it A LOT over the past year or so. So thank you for your work on it.
