Refreshing a data table after changing its FTableRowBase

I’m building data driven elements into my game using data tables. What I’ve found is that when I alter my derived FTableRowBase (adding a new column, for instance), those changes are not reflected in the editor. I have to create a brand new table and re-enter all the data each time. The only thing I see that’s akin to a refresh button is the reimport option, but I’m entering my values through the editor and not importing from an external file, so I have nothing to reimport. I’m sure I’m just missing something obvious. Anyone know how to refresh it?
