如何在Java中使JTable可编辑 [英] How do I make a JTable editable in java

问题描述

我在Java中使用JTable，但是它不允许我编辑单元格.

I'm using a JTable in java, but it won't let me edit the cells.

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);

推荐答案

添加以下代码

 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);
  }

您应该有一个数组，用于保存更改

you should have a array where you will save the changes
