java - Set part of JTable cells uneditable -

i created jtable in eclipse using "design" option , want make cells uneditable. code:

    public frame(int choice) {        initcomponents();        defaultmodel = (defaulttablemodel) m0.getmodel();        if (choice == 0) {         defaultmodel.setcolumncount(7);         defaultmodel.removerow(6);        }     defaultmodel.iscelleditable(2,2);     defaultmodel.iscelleditable(3,3);  } public boolean iscelleditable(int row, int column) {     return false; } 

cells (2,2) , (3,3) should uneditable. not work. can help?

do see problem here?:

public boolean iscelleditable(int row, int column) {     return false;  // !!!!!!! } 

cells (2,2) , (3,3) should editable. not work. can help?

you're setting cells ineditable iscelleditable(...) method override , you're inexplicably wondering why they're not editable. sorry that's bit crazy. solution change returned iscelleditable(...) method want to. if want editable 2,2 , 3,3, put logic in method above.

see you've edited question is:

public boolean iscelleditable(int row, int column) {     return false; } 

cells (2,2) , (3,3) should uneditable. not work. can help?

that of course changes everything. guess iscelleditable not true override of jtable or model. have tried adding @override annotation before it? can show how in fact overriding current jtable or model? need show method in class extends jtable or model , in fact class being used.
