Hello,
There is the new tables feature in spreadsheet: https://support.google.com/docs/answer/14239833?hl=en
I tried to import a sheet only containing a table but I got: “No columns foundTables must specify a column structure. For some reason, the app definition has been corrupted. It may also be possible that you left your column structure in an inconsistent state. Delete and re-add the table to create the column structure.”
Will this feature be supported in the future/near future?
