我按照以下方式创建了 jTable：

public void refTable(String jobNo) {
        Report rp = new Report();
        final String noJob = jobNo;    
        Map<Integer, String> jMap = rp.getReportInfo(jobNo);
        Map<Integer, String> sortedMap = new TreeMap<Integer, String>(jMap);    
        String[] row = new String[sortedMap.size()];
        Integer[] no = new Integer[sortedMap.size()];
        String[] stat = new String[sortedMap.size()];
        Boolean[] dev = new Boolean[sortedMap.size()];
        String[] remark = new String[sortedMap.size()];
        Boolean[] rem = new Boolean[sortedMap.size()];
        String userRemark[] = new String[sortedMap.size()];
        tabSize = sortedMap.size();
        int i = 0;

        for (Integer key : sortedMap.keySet()) {
            no[i] = key;
             String []val = sortedMap.get(key).split("###");
            if (val[0].trim().equals("DEV")) {
                stat[i] = "FAIL";
            } else {
                stat[i] = val[0].trim();
            }

             String []strRemark = val[1].split("No");
             //tempRemark = strRemark[0];
             RemarkDropDownList.devTempValue =val[1].split("No");

            row[i] = strRemark[0].trim().replaceAll("Yes", "");//
            //row[i] = val[1].trim();
            if(strRemark.length<2)
            dev[i] = false;
            else
            dev[i] = true;    
            remark[i] = "";
            if(strRemark.length<2)
            userRemark[i] = "";
            else
                if(RemarkDropDownList.userOthersReamrk!=null)
            userRemark[i] = RemarkDropDownList.userSelectedItem;   
            else
              userRemark[i] = strRemark[1];      
            //remark[i] = false;
           /*if(userRemark1[i]!=null)
            userRemark[i] = userRemark1[i];//RemarkDropDownList.userOthersReamrk;
            else
            userRemark[i] ="";   Use when drop down*/
            rem[i] = false;
            i++;
        }

        DefaultTableModel model = new DefaultTableModel();
        model.fireTableDataChanged();
        jTable1.setModel(model);    
        model.addColumn("No:", no);
        model.addColumn("Status:", stat);
        model.addColumn("Details:", row);
        model.addColumn("Non-Deviation", dev);
        model.addColumn("Remarks", remark);
        model.addColumn("Remove", rem);
        model.addColumn("UR", testRemark);

        TableColumn col1 = jTable1.getColumnModel().getColumn(0);
        col1.setPreferredWidth(30);

        TableColumn col2 = jTable1.getColumnModel().getColumn(1);
        col2.setPreferredWidth(30);

        TableColumn col3 = jTable1.getColumnModel().getColumn(2);
        TextRenderer renderer = new TextRenderer();
        col3.setCellRenderer(renderer);
        col3.setPreferredWidth(350);

        CellRenderer cellRender = new CellRenderer();
        TableColumn col4 = jTable1.getColumnModel().getColumn(3);
        col4.setCellEditor(jTable1.getDefaultEditor(Boolean.class));
        col4.setCellRenderer(cellRender);
        col4.setPreferredWidth(50);

        TableButton buttonEditor = new TableButton("Button");
        buttonEditor.addTableButtonListener(new TableButtonListener() {
            //@Override
            public void tableButtonClicked(int row, int col) {
                RemarkDropDownList rmk = new RemarkDropDownList(noJob, row);
            }
        });
        TableColumn col5 = jTable1.getColumnModel().getColumn(4);
        col5.setCellRenderer(buttonEditor);
        col5.setCellEditor(buttonEditor);  
        TableColumn col6 = jTable1.getColumnModel().getColumn(5);
        col6.setCellEditor(jTable1.getDefaultEditor(Boolean.class));
        col6.setCellRenderer(jTable1.getDefaultRenderer(Boolean.class));
        col6.setPreferredWidth(50);
        jTable1.setShowGrid(true);
        jTable1.setGridColor(Color.BLACK);
        jTable1.setAutoCreateRowSorter(true);
       }

我试图从像这样的同一类中的不同函数中清除 jTable。

public void clear()
{
jTable1.setModel(new DefaultTableModel());
}

jTable 未按预期清除。当我尝试移至jTable1.setModel(new DefaultTableModel());主功能refTable()时，jTable 已清除。另外，我不仅能够清除jTable，而且看起来我根本无法访问jTable。请指教。

这将为您清理表格。您必须首先创建新的默认表模型，然后对其进行设置，最后将行数设置为 0。

public void clear(){

 DefaultTableModel tm=new DefaultTableModel();
 jTable1.setModel(tm);
 tm.setRowCount(0);
}

希望这有帮助。
