Well this is for sure not easy to solve with HTML for Evernote... My workarounds: Regarding "simple" tables (max 6*6) in Evernote: Go the end of the table, ie. the next free line of space after the table. Add table in same design as current table. The new table will join the existing table. Complex tables / sheets: Host your worksheet in external solutions. I use Google Sheets. Insert link to your sheet in the Evernote note.
