Tables are a wart on Excel. They don't fit the established idioms at all. There's a very long list of common & simple things that either break or get very clunky with tables, including:
- Multi-row headers - Merged-cell headers - Headers with the same name (sometimes useful) - Formulas that cross rows (e.g. iteratively refer to the previous row) - Different table sections (e.g. a table-width merged row with one header) - Merged rows
The benefit of tables is ... what? Slightly simpler formulas when all operands are in the same row? More automatic (and annoying) formatting? Almost everything people try to do with Tables is actually easier without them, and if it's not, you really just want a database.
