[Pytables-users] How to modify a value in a table?

[Philou <Kal...@wa...>]

Hi list,
I successfully load an hdf5 file, displays values in a spreadsheet, 
modify the spreadsheet, get the modifyied value.
Now, i was wondering whether it was possible to modify only a value in a 
table.

I look in the pytables tutorial and find a way to append a row but not 
to modify a value in an existing row.

If it is not possible, is it possible to remove a row and append another 
row at the same position? (Is the fact of deleting a row letting empty 
space?).
Thanks a lot for your help,
Philippe Collet
