java - JTable Is not Adding Vector on Click Event of Label -

i have jtable , have set vector header , vector of vector row content has add together header onclick event. when tried add together string vector in click event adding string vector vector not added header how can create have used firetablechanged event of model. not working how.

here sample code.

vector vector; vector<vector> vector_content; table = new javax.swing.jtable(); table.setmodel(new defaulttablemodel(vector_content,vector){ private static final long serialversionuid = 1l; @override public boolean iscelleditable(int row, int column) { homecoming false; } });

now have click event m adding info header table of content.

vector = new vector(); vector_content = new vector<vector>(); vector.add("employee name"); vector.add("date"); vector.add("type");

data added vector can print info how not set table how can create it?

example here working because have added table model using col vector , row when utilize in button click not working method name ![setdate();][1]

defaulttablemodel has number of helpful methods, 1 of addcolumn...

tablemodel model = (defaulttablemodel)table.getmodel(); model.addcolumn("employee name"); model.addcolumn("date"); model.addcolumn("type");

if want remove existing columns, can utilize setcolumncount , pass 0 first

updated based on additional example

basically, did , worked fine...

jtable1.gettableheader().addmouselistener(new mouseadapter() { @override public void mouseclicked(mouseevent e) { defaulttablemodel model = (defaulttablemodel) jtable1.getmodel(); model.setcolumncount(0); model.addcolumn("banans"); model.addcolumn("apples"); model.addcolumn("pears"); model.addcolumn("fluffy"); model.addcolumn("unicorns"); } });

you should never modify state of info model might relying out side model, doing potentially place ui unstable state
