hi,
is there any way to tell Spire.XLS to use the classic layout for pivot table?
haw i can say Spire.XLS to adjast column width in pivot table?
what is the command to compress / expand the fields in the pivot table?
I can add a calculated column with the difference between two columns in pivot table?
i try << pt.PivotTables(0).CalculatedFields.Add("Delta %", "Ricavi-Costi") >>
but the function returns the error << Riferimento a un oggetto non impostato su un'istanza di oggetto. >>
Why?
There is a manual for Spire.XLS with all the functions and usage?
thanks in advance
