上图
数据都填充进去了 但是 列名不显示 如何解？ // 表格
private JTable ivtable; private JTable getTableDS() {
if (ivtable == null) {
String[] headers = { "XX编码", "XX编码", "XX编码", "XX编码", "XX编码",
"成本1", "成本2" };
Object[][] cellData = null;
DefaultTableModel model = new DefaultTableModel(cellData, headers) {
public boolean isCellEditable(int row, int column) {
return false;
}
};
ivtable = new JTable(model);
ivtable.setName("TableDS");
ivtable.setBounds(39, 115, 750, 290);
ivtable.setRowHeight(20);
ivtable.setSelectionMode(0);
JScrollPane scrollPane = new JScrollPane(ivtable);
}
return ivtable;
}
我也加了
JScrollPane scrollPane = new JScrollPane(ivtable);为什么 还不显示 列头？还有java的Jtable 有没有 多选 全选？求达人。

即是说，你在将表格添加到容器的时候，你返回的是JTable,虽然你在方法里面有
JScrollPane scrollPane = new JScrollPane(ivtable);
但是你最终还是直接将表格添加到容器里面去了，而不是将包含有表格的scrollPane添加到容器里面，那么你上面这句代码就等于没写，所以仍然没有表头
DefaultTableModel model = (DefaultTableModel) ivtable.getModel();
model.setColumnIdentifiers(hearders);
答对了请给分，我急用！！！
headers是一个数组，也就是你的String[] headers = { "XX编码", "XX编码", "XX编码", "XX编码", "XX编码","成本1", "成本2" };
我放到JPanel里了 但是也不行。 JScrollPane scrollPane = new JScrollPane(ivtable);
scrollPane.setBorder(new BevelBorder(BevelBorder.LOWERED));
add(scrollPane);
String[] headers = { "公司编码", "部门编码", "存货编码", "客户编码", "结算方式编码",
"成本1", "成本2" };
Object[][] cellData = null;
DefaultTableModel model = new DefaultTableModel(cellData, headers) {
public boolean isCellEditable(int row, int column) {
return false;
}
};
ivtable = new JTable(model);我这么加 也一样把。
你的不行啊。.. 难道是 我继承的是JPanel的原因？extends UIPanel？ private JTable getTableDS() {

"成本1", "成本2" };

ivtable.setRowHeight(20);
ivtable.setSelectionMode(0);
JScrollPane scrollPane = new JScrollPane(ivtable);
scrollPane.setBorder(new BevelBorder(BevelBorder.LOWERED));
add(scrollPane);

return ivtable;

基本就这些了。

ivtable.setName( "TableDS ");
ivtable.setBounds(39, 115, 750, 290);
ivtable.setRowHeight(20);
ivtable.setSelectionMode(0); JScrollPane scrollPane = new JScrollPane(ivtable);
scrollPane.setBorder(new BevelBorder(BevelBorder.LOWERED));
add(scrollPane);
}
return ivtable;
}
public ImportInvCostUI() {
initialize();
}
private void initialize() {
try {
setName( "EAIDataTrafficUI ");
setLayout(null);
setSize(738, 464);
add(getJPanel1(), getJPanel1().getName());
add(getJLabelSelect(), getJLabelSelect().getName());
add(getSrcFilePath(), getSrcFilePath().getName());

} catch (Throwable ivjExc) {

}
}
发现神奇的地方了。。
不加上 setLayout(null); 就能出来了
但是加上就不行了。
