效果

export type columnitemtype = {
   title:string // 列名
   dataindex?:string // table data key 值 
   width?:number // 列 宽度
   slotkey?:string // 插槽作用域 id
   sortable?:boolean //是否 支持排序
   align?: 'left'|'center'|'right' // 布局
   key?:string // 哪个列数据 作为 唯一key 值 默认 index
   render?:(h:rendertype,row:any)=>void // 自定义render
   
}
type propstype = {
  mintableheight?: number; //表格最小高度
  rownum?: number; // 表格显示几行
  headerheight?: number; // 头部默认高度
  rowheight?: number; //每行数据的默认高度
  column: array<columnitemtype>;
  tabledatas: array<any>;
  isclick?: boolean; // 是否需要触发行点击事件
  disable?: boolean; // 是否启用下拉加载
  error?: boolean; // 数据加载失败
  loading?: boolean; // 数据处于加载状态
  finish?: boolean; // 数据 是否完全加载
  loadingtext?: string; // 加载文案
  errortext?: string; // 失败文案
  finishedtext?: string; // 完成文案
  offset?: number; //触发加载的底部距离
  rootvalue?: number; //  
};

更新日志

2023.9.27

1. 修改transform 渲染方式 不经过 vue 派发更新（数据量过大 会有卡顿），直接用原生js 去控制
   具体表现如下图（1000条列表数据）
   
   在左右滑动1s内 有300多ms 消耗到 vue3 的派发更新上，但是我们人为是知道只有组件样式需要改变，所以可以考虑优化 ，将更新的操作用原声js 实现 ，不走vue 响应更新

vue派发更新时间就省略了，响应速度提高了200多ms。就基本不会卡顿了

2. 增加 rootvalue 配置 默认75（基于rootvalue 去将 props 中的 一些 长度单位 传化成 rem） 修复pad 样式问题（保持和 postcsspxtorem 插件配置一致 ）
   postcsspxtorem({
   // 自适应，px>rem转换
   rootvalue: 75, // 75表示750设计稿，37.5表示375设计稿
   proplist: [“*”], // 需要转换的属性，这里选择全部都进行转换
   selectorblacklist: [“norem”], // 过滤掉norem-开头的class，不进行rem转换
   }),
3. 优化一些参数命名
4. 将点击 显示操作栏目的操作 更多内置化，便于使用
