My suggestion a long while ago was that there should be a facility to insert table data from an external source.  After several upgrades this has not happened.  I am running a soccer website which requires inserting fixture details for 4 teams.  I used to use a very old Dreamweaver (v4) which had a facility to import tabular data, e.g. an Excel .txt file.  So easy that way.  Having to enter it all in piece by piece is time consuming.  I am baffled to understand why you cannot incorporate the same facility as Dreamweaver did many years ago.
