如何在java中編輯JTable

Question

我在java中使用了JTable，但它不會讓我編輯單元格。

private final TableModel dataModel = new AbstractTableModel() { 

     public int getColumnCount() { 
      return 5; 
     } 

     public int getRowCount() { 
      return 10; 
     } 

     public Object getValueAt(int row, int col) { 
      return new Integer(row*col); 
     } 
}; 

private final JTable table = new JTable(dataModel); 

Answer 1

添加follwoing代碼

public boolean isCellEditable(int row, int col) 
     { return true; } 
public void setValueAt(Object value, int row, int col) { 
    rowData[row][col] = value; 
    fireTableCellUpdated(row, col); 
    } 

你應該有一個數組，你可以將更改保存

Answer 2

添加匿名內部類AbstractTableModel

public boolean isCellEditable(int row, int col) { 
    return true; 
} 

Answer 3

嘗試內isCellEditable()功能

private final TableModel dataModel = new AbstractTableModel() { 

     public int getColumnCount() { 
      return 5; 
     } 

     public int getRowCount() { 
      return 10; 
     } 

     public Object getValueAt(int row, int col) { 
      return new Integer(row*col); 
     } 

     public boolean isCellEditable(int row, int col) { 
        return true; 
       } 
}; 

Answer 4

將isCellEditable（）添加到希望它們可編輯的行和列中，例如，如果不希望某些列如ID可編輯，則返回false。請記住，你需要一些保存editit數據，其中

public boolean isCellEditable(int row, int col) { 
     return true; // or false for none editable columns 
    } 
public void setValueAt(Object value, int row, int col) { 
    rowData[row][col] = value; // save edits some where 
    fireTableCellUpdated(row, col); // informe any object about changes 
}
