问题描述
我有点困惑.我正在尝试更新JTable,但是没有更新.这是我目前的代码:
I have little confusion. I am trying to update JTable, but the updates are not coming up. This is my present code:
private void addTable(){
table = new JTable();// the table for 'Benchmark' tab
table.setShowVerticalLines(false);
table.setBorder(null);
data = new Object[][] {
{"Key", ""},//result[0]
{"Precision", ""},//result[2]+" %"
{"Cipher", ""},//result[4]
{"Language", ""},
{"Performance", ""},//result[3]
};
String [] header = new String[] {"Subject of Interest", "Output"};
model = new DefaultTableModel(data, header);
table.setModel(model);
table.getColumnModel().getColumn(0).setPreferredWidth(136);
table.getColumnModel().getColumn(1).setPreferredWidth(550);
GroupLayout gl_panelBenchmark = new GroupLayout(panelBenchmark);
gl_panelBenchmark.setHorizontalGroup(
gl_panelBenchmark.createParallelGroup(Alignment.TRAILING)
.addComponent(textInfoCrypto, GroupLayout.DEFAULT_SIZE, 759, Short.MAX_VALUE)
.addGroup(gl_panelBenchmark.createSequentialGroup()
.addGap(10)
.addComponent(textPane, GroupLayout.DEFAULT_SIZE, 739, Short.MAX_VALUE)
.addGap(10))
.addGroup(Alignment.LEADING, gl_panelBenchmark.createSequentialGroup()
.addContainerGap()
.addComponent(table, GroupLayout.DEFAULT_SIZE, 739, Short.MAX_VALUE)
.addContainerGap())
);
gl_panelBenchmark.setVerticalGroup(
gl_panelBenchmark.createParallelGroup(Alignment.LEADING)
.addGroup(gl_panelBenchmark.createSequentialGroup()
.addContainerGap()
.addComponent(textInfoCrypto)
.addPreferredGap(ComponentPlacement.UNRELATED)
.addComponent(textPane, GroupLayout.PREFERRED_SIZE, 41, GroupLayout.PREFERRED_SIZE)
.addPreferredGap(ComponentPlacement.UNRELATED)
.addComponent(table, GroupLayout.PREFERRED_SIZE, 79, Short.MAX_VALUE)
.addContainerGap())
);
panelBenchmark.setLayout(gl_panelBenchmark);
}
这就是我现阶段要更新的一行的方式.下面的代码已从另一种方法调用:
And this is how I am trying to update, at this stage, a single row. The below code has been invoked from another method:
data[0][0]= result[0];
model.fireTableCellUpdated(0, 0);
在此阶段,我只能看到包含行名的表框架,而没有数据.有什么帮助吗?
At this stage I can see only the table frames including row names, but no data. Any help, please?
推荐答案
data
只是表模型中未包含的本地数据.您需要使用:
data
is only local data not contained in the table model. You need to use:
tableModel.setValue(result [0],0,0);
