有谁知道如何在我的React数据网格中添加可调整大小的列？

可以使用react-data-grid包来添加可调整大小的列。使用react-data-grid时，在ColumnDefinitions中设置resizable为true即可创建可调整大小的列。以下是具有可调整大小列的React数据网格示例代码：

import React from "react";
import ReactDataGrid from "react-data-grid";

const data = [
  { id: 1, title: "Task 1", priority: "High" },
  { id: 2, title: "Task 2", priority: "Normal" },
  { id: 3, title: "Task 3", priority: "Low" },
  { id: 4, title: "Task 4", priority: "High" }
];

const columns = [
  { key: "id", name: "ID", resizable: true }, // 设置resizable为true
  { key: "title", name: "Title", resizable: true },
  { key: "priority", name: "Priority", resizable: true }
];

function Example() {
  return (
    <div style={{ height: 250 }}>
      <ReactDataGrid columns={columns} rowGetter={i => data[i]} rowsCount={data.length} />
    </div>
  );
}

export default Example;
