I just updated to 17.1, and noticed that I was unable to copy Global Tables using Ctrl+C as I was able to in 17.0.
Upon further inspection, it looks like Global Tables that are stored as bundles are unable to be copied with Ctrl+C, and tables that are not stored as bundles are able to be copied, but when pasted into Excel it looses it's column definitions (everything is put into one column without any delimiters)
Also, as a side note, I noticed that when you right click on a node and choose Explore->As Table, if that node contains subnodes, or if it is a bundle that contains multiple entries, then the number of subnodes, or entries, is printed to the output console
