Hello,
I’d like to report some bugs and a behaviour difference with Excel.
OS version: Windows 10 21H2
App version: OnlyOffice Desktop v7.0.0.127
Downloaded from: ONLYOFFICE website
#1 Formula’s using the same sheet table name are not updated when copying sheet
I have a sheet with a table. Next to the table, I have this formula using the table name, eg :
=SUM(Table_2204[Hours])
When I copy the sheet, a new name is given to the table,
Eg “Table1”
But the cell with formula referencing the table on the same sheet is not updated.
The cell’s formula is still :
=SUM(Table_2204[Hours])
Whereas I would expect the same sheet table name to be updated, eg:
=SUM(Table1[Hours])
#2 Column name using ’ (apostrophe) are handled differently with Excel, breaking compatibility
I have a table using an apostrophe in a column name: “Nb d’heures” (Nb of Hours).
When referencing to this column, ONLYOFFICE use the exact name:
=SUM(Table[Nb d'heures])
But Excel uses a double apostrophe to reference the same column in formulas:
=SUM(Table[Nb d''heures])
If I edit this formula in ONLYOFFICE, an error is produced:
If I fix the formulas to have only one apostrophe, Excel doesn’t recognize anymore this reference :
Screenshot showing #REF instead of formula’s result
Formulas using the single apostrophe have been changed by Excel in =SUM(#REF!) the formulas are lost 
#3 Renaming a Table name is not working
I tried to rename a table name in the Name Manager, I can edit the name, but when I click OK, the name is not changed.
Thanks for your attention and big thanks for your work on ONLYOFFICE!
