Javascript Pevent触发material 用户界面数据网格中的自动保存

我判断了你的代码，似乎只有多个添加的行有相同的ID 10的问题，在我使用state变量count来管理ID字段后，输出看起来很好，希望它解决了你的问题，如果我的答案没有帮助，请分享堆栈闪电战复制的问题！

...
function EditToolbar(props: EditToolbarProps) {
  const [count, setCount] = React.useState(10); // <- changed here
  const { setRows, setRowModesModel } = props;

  const handleClick = () => {
    setCount(() => count + 1); // <- changed here
    setRows((oldRows) => [
      ...oldRows,
      { id: count, name: '', age: '', isNew: true },
    ]);
    setRowModesModel((oldModel) => ({
      ...oldModel,
      [count]: { mode: GridRowModes.Edit, fieldToFocus: 'name' }, // <- changed here
    }));
  };
