I had like to implement a multi-row JTableHeader with ...
. - A row with column titles; some of them are replaced by a JComboBox - E.g. "Under the power range", "Only in the power range", "Above the power range", "Total"
. - A row for the column units - E.g. "KW", "MWH", "Hours"
. - A row for regrouping titles - E.g. "Electricity", "Heat"
How to achieve this ?
Which Swing topics do I need to study ?
Where can I find an example SSCCE ?
