DropTables allows for users to login and manage data tables. It is a good replacement for Google Sheets. You can import/export Google sheets and Excel spreadsheets. Drop Tables also has some great themes for front facing price tables. Front facing tables can also be created from data used in other Joomla tables. This can be a real game changer for websites that need some easy, affordable extra data features.
