Answer 1

我弄了个线程单独在跑的一段代码：Object[] columnNames = {"相","电压(V)","电流(A)","功率因素", "有功(KVA)","无功(KVar)","单相电容",
                "电压总畸变率","电压3次谐波","电压5次谐波","电压7次谐波","电压9次谐波","电压11次谐波"};
        Object[][] data = {{ "A", APhaseVoltage, APhaseCurrent,APhaseRate, AActive,AReactive,
                APhasePoints,APhaseVolTotalDistortion,APhaseThreeVolHarmonicRatio,
                APhaseFiveVolHarmonicRatio,APhaseSevenVolHarmonicRatio,APhaseNineVolHarmonicRatio,
                APhaseElevenVolHarmonicRatio},{"B",BPhaseVoltage, BPhaseCurrent,BPhaseRate,
                BActive,BReactive,BPhasePoints,BPhaseVolTotalDistortion,BPhaseThreeVolHarmonicRatio,
                BPhaseFiveVolHarmonicRatio,BPhaseSevenVolHarmonicRatio,BPhaseNineVolHarmonicRatio,
                BPhaseElevenVolHarmonicRatio},{"C",CPhaseVoltage, CPhaseCurrent,CPhaseRate,
                CActive,CReactive,CPhasePoints,CPhaseVolTotalDistortion,CPhaseThreeVolHarmonicRatio,
                CPhaseFiveVolHarmonicRatio,CPhaseSevenVolHarmonicRatio,CPhaseNineVolHarmonicRatio,
                CPhaseElevenVolHarmonicRatio}};
        dataModel.setDataVector(data,columnNames);
        showTab.getTableHeader().setReorderingAllowed(false);
        showTab.setAutoResizeMode(javax.swing.JTable.AUTO_RESIZE_OFF);
        showTab.setModel(dataModel);

Answer 2

dataModel是一个DefaultTableModel;
showTab是一个JTable;

Answer 3

Debug没任何错误，就是给它个线程自己跑时会跳错，不过程序运行倒是正常的
