java - How to add a row to JTable after populating data using DbUtils.resultSetToTableModel? -

i have jtable defined in way:

public jtable table_1; model_3 = new defaulttablemodel();  table_1 = new jtable(model_3);   scrollpane_5.setviewportview(table_1); 

add row:

model_3.addrow(new object[]{table.getvalueat(row,0) , table.getvalueat(row,1) ,table.getvalueat(row,2) , commentfood }); 

remove row:

model_3.removerow(row);  //row integer 

until here, used work properly. can see table defined public because need fill jframe in way:

takeorder = new takeorder(); //get data db resultset to.table_1.setmodel(dbutils.resultsettotablemodel(resultset)); 

if fill table in way , try add or remove model_3, not work! suggestion how can add or remove table after using dbutils.resultsettotablemodel(resultset) appreciated.

as couldn't find information on internet , saw couple of people asked same question no answer. came solution:

if (formout) {     (int = 0; < table_1.getrowcount(); i++) {         model_3.addrow(new object[]{table_1.getvalueat(i,0),              table_1.getvalueat(i, 1), table_1.getvalueat(i, 2)});     } }  formout = false; table_1.setmodel(model_3); 

fromout boolean check if have used model table. if add data table previous model, , reference model table. can add model well.
