Hi,

the figures to get a numerical total.

thanks

Access the column cells, get their text contents, convert to doubles, add
them together. Like you, speaking hypothetically.

Instead of asking hypothetical questions, why not post your code and ask
real ones?

Because I am very pressed for time and wondered if there was any example
code out there - I have searched but didn't come accross anything

Iterate (loop) over the column data in the model, not in the JTable.
