替换jtable的内容

Question

我有一个使用NetBeans IDE的swing桌面应用程序应用程序有一个显示的JTable来自lucene搜索操作的数据。

任何时候进行新的搜索，表将新的搜索结果追加到前一个搜索结果。我想要的是桌子取代任何退出搜索结果与新的搜索结果。为了为表刷新单词并显示新的搜索结果。

有什么建议吗

这是数据模型

的代码片段

public class MyTableModel extends AbstractTableModel {
    private Vector<Vector<String>> dataList = new Vector<>();
     private String[] header = { "ID","SUBJECT","LETTTER FROM","LETTER DATE","DATE RECEIED",
                                  "REMARKS","DATE DISPATCHED","DESTINATION OFFICE"};

    public Vector<Vector<String>> getDataList() {
        return dataList;
    }
    public void setDataList(Vector<Vector<String>> dataList) {       
        this.dataList = dataList;
        fireTableDataChanged(); 
    }
    public void setHeader(String[] header) {
        this.header = header;
    }
    public String[] getHeader() {
        return header;
    }
    @Override
    public int getRowCount() {
        return dataList.size();
    }
    @Override
    public int getColumnCount() {
        return header.length;
    }
    @Override
   public String getColumnName(int col) {
    return header[col];
   }
    @Override
    public Object getValueAt(int row, int col) { 
    return dataList.get(row).get(col);
    }
}

此代码将搜索结果传递给数据模型类

private void searchButtonActionPerformed(java.awt.event.ActionEvent evt) {                                             
    try {
        searchField = searchTextField.getText();
        if(!searchField.isEmpty())
        {                
       matrix = dbs.searchDatabase(searchField + "*");
       myModel.setDataList(matrix);
        }
    } catch (CorruptIndexException ex) {
        Logger.getLogger(GNSSJFrame.class.getName()).log(Level.SEVERE, null, ex);
    } catch (LockObtainFailedException ex) {
        Logger.getLogger(GNSSJFrame.class.getName()).log(Level.SEVERE, null, ex);
    } catch (IOException | ParseException ex) {
        Logger.getLogger(GNSSJFrame.class.getName()).log(Level.SEVERE, null, ex);
    }             
}

Answer 1

如果您的表模型是这样的，

class AllTableModel extends AbstractTableModel {
    // Suppose this is the data list table is using,
    List<TableData> tableData = new ArrayList<TableData>();
    // Override methods goes here.
    public void setTableData(List<TableData> tableData) {
        this.tableData = tableData;
        fireTableDataChanged();
}  
}

现在，使用表模型实例将新数据设置到列表中。

 allTableModel.setTableData(/* Set new search results to the list.*/);
