check modified rows in a table

Hi everyone,
I have a table in editable mode. How can I detect if at least a row is modified?
myTable.isModified() always returns false.
And iterating over the rows, how can I check if each row is modified?

Thank you, Francesco

Table.isModified() has a confusing name and does not do what you thinkā€¦

There is an explanation and some code samples in this
to achieve what you want.

Thank you Mathias.
Now I can detect if a table is modified; my following question is: when modified, how can I get the modified rows?
