There’s a reason the “Legacy” Table Visualization is still kicking around (for how long? 1 year? 2?)… The “New” Table Visualization needs some serious work!
Could Looker please please please invest into getting the “New” Table Visualization up to snuff because the Legacy one has been neglected to the point that it completely buggers out in some cases (e.g. with both Row and Column totals), and this alternative isn’t really working either.
