二维数组循环赋值

Object[][] objArr2 = new Object[ltt.size()][4];

            for(int i=0; i<ltt.size();i++){
                objArr2[i] = new Object[4];
                objArr2[i][0] = ltt.get(i).getTaskId();     
                objArr2[i][1] = ltt.get(i).getTaskName();
                objArr2[i][2] = ltt.get(i).getUserId();
                objArr2[i][3] = "删除";
            }
