提问by Tomi S
+-------+------+------+
| name | level| score|
+-------+------+------+
| data | data | data |
+-------+------+------+
This is how I would like to show in JTable.
这就是我想在JTable.
//SQL
//SQL
static String[][] executeQuery(){
blabla;
rs = stmt.executeQuery(sql);
int i=0;
while(rs.next()){
query[0][i++] = rs.getString("name ");
query[1][i] = rs.getString("level");
query[2][i] = rs.getString("score");
}
return query;
}
//MAIN
JPanel panel = new JPanel();
String[][] getScores = executeQuery();
Object[][] data = getScores ;
String[] columnNames = {"name ","level","score"};
JTable table = new JTable (data, columnNames);
table.setEnabled(false);
panel.add(table);
JOptionPane.showMessageDialog(null, panel);
Result of this is is 3x3 table which is not properly oriented. Dont know why?
My question is: do you have some other example or do you see some errors i made ..
I have only this example but its too complicated for me - beginner:

这样做的结果是 3x3 表，它没有正确定向。不知道为什么？
我的问题是：您有其他示例吗，或者您是否看到我犯的一些错误..
我只有这个示例，但对我来说太复杂了 - 初学者：http:

The easiest way is to add the data to a DefaultTableModel. See the "Table From Database Example" code found in the Table From Databasearticle.
最简单的方法是将数据添加到 DefaultTableModel。请参阅Table From Database文章中的“Table From Database Example”代码。
