空数据表格

当 list 为空时显示空态，可通过 emptyText 自定义提示文案。

使用的 API

type Column = {
  key: string;  // 列标识(必填)
  title: string;  // 列标题(必填)
  width: number;  // 列宽(必填)
}

type Options = {
  list: T[];  // 数据列表
  itemKey: string;  // 行唯一标识字段名
  estimatedSize: number;  // 行预估高度(px)
  buffer: number;  // 缓冲区行数
  border: boolean;  // 是否显示边框
  emptyText: string;  // 空态文案
}
