将String从String更改为复选框(JTable)

首先,您必须在模型中将数据保存为布尔值.所以你应该用它rs.getBoolean("Fanta")代替rs.getString("Fanta").trim().

其次,你必须覆盖你的public Class getColumnClass(int column)方法JTable.您的代码可能如下所示:

JTable orderResults = new JTable() {
    @Override
    public Class getColumnClass(int column) {
        // first 5 columns will be represented as an checkbox
        if(column <= 4){
            return Boolean.class;
        }

        // rest of them as a text
        return String.class;
    }
};
