connect in tablewidget, listwidget and lambda with arguments

Some question was on IRC about connect in tablewidget, listwidget (as interactive widgets with data) and lambda with arguments. I made quick test and looks that exist problem with this type widgets when need send data in case that widget sending own structure.

Eg. tablewidget has index for row, column, data, etc.

When with this want sent in example identification as string or name widget, then not working nothing around sending data in case sending index as normaly without for clicked - yes, without lambda.

Is this bug or normal decision that we can do this by lambda?

If this was intentional, then if many widgets and functions must be dedicated, then is problem to easy solve it. After PySide2 replacing PyQt developers are confused.
