java - Multiple editable rows in JTable header -

i need have multiple editable rows in jtable header, same header column contain both jtextfield , jbutton.

i have found how implement editable header cells , how split header cells. turned out these approaches different , need fuse them one.

is there multiple editable jtable header rows solutions developed , wouldn't need reinvent bicycle?

what have found far:

• just idea use tablecelleditor in jtableheader wrong, nor multi_line_header, buy jide (support)

• simpler possible use rowfilter jtextfield,

• note don't forget convert indexes view coordinates model coordinates
