Hi,
I'm seeking a solution for this problem
I have a custom Column type
number with coma and for any reason i would add a value for theese cell after selected some row in the library
exemple :
in column Indice a have
Sel Indice | Book
> 1 | a book
> 6 | book 2
3 | book 3
> 9 | book 4
after applying add 2 for column indice on selected 1,2 and 4 book i would obtain :
> 3 | a book
> 8 | book 2
3 | book 3
> 11 | book 4
and the same thing on a colum type like serie with index
Is there an existing solution in calibre or this must done by a plug-in ?
thank in advance
regards
Khan-Dam
