Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

乐高系列之 virtualTable 组件

npm (scoped)

基于运营平台[email protected]的交互要求,在ant-design-vue table组件的基础上进行二次封装的虚拟滚动表格,建议配合 @pluve/use-antd-table-vue 使用。

@pluve/use-antd-table-vue 已经投入了我们的生产环境中使用,经受住了来自真实业务的考验,并伴随着我们的业务需求不断完善。

特性

  • 能支撑10万+数据展示和交互
  • 性能优越,豪秒级渲染
  • 使用简单,0负担改造现有表格

缺点

所有行必须等高; 不能使用合并行,展开行,合并列等 原有table里的函数注入的参数index不准确,需要使用导出的方法'getStartRowIndex'获取开始行得到当前行标 getStartRowIndex()+index

默认配置

| 属性 |类型|默认值 | 描述 | | --- | --- | --- | | rowHeight | Number | 必填|当前表格行高 | | dataSource | Array | 必填| 注入数据 | | scroll | { x:number, y:number} | 必填| 表格宽高 | |rangeStep| number | 10| 实际渲染的队列长度,需要铺满y的高度,数值越大性能越差 |

方法

| 名称 | 参数 |描述 | | --- | --- |I | scrollTo | rowIndex| 滚动表格到多少行 | | tableRef| 表格实例| 可使用antd表格方法 | |getStartRowIndex|无|获取到当前开始渲染行 currentRowIndex = getStartRowIndex()+index;

表单校验

1.支持继承antdV table 的所有API 2.原表格函数index不准确,需要配合 getStartRowIndex使用 3。不能使用合并行,展开行,合并列等

安装

# 使用 npm
npm i @pluve/lego-lego-virtual-table-vue

# 使用 yarn
yarn add @pluve/lego-lego-virtual-table-vue

使用

<template>
   <LegoVirtualTable ref="tableRef" :columns="columns" :data-source="data" :enable-virtual="true" :row-height="55" :range-step="15"
      :scroll="{ y: 400, x: 1500 }">
      <template #action="{index:rowIndex,record}">
        <a>action {{ rowIndex }}</a>
      </template>
    </LegoVirtualTable>
</template>

<script setup lang="ts">
import { message } from "ant-design-vue";
import { reactive,ref } from "vue";
import LegoVirtualTable from "./components/index.entry";

interface DataItem {
  key: number;
  name: string;
  age: number;
  address: string;
}

const columns: any[] = [
  { title: 'Full Name', width: 100, dataIndex: 'name', key: 'name', fixed: 'left',ellipsis:true },
  { title: 'Age', width: 100, dataIndex: 'age', key: 'age', fixed: 'left' },
  { title: 'Column 1', dataIndex: 'address', key: '1', width: 150,ellipsis:true  },
  { title: 'Column 2', dataIndex: 'address', key: '2', width: 150,ellipsis:true  },
  { title: 'Column 3', dataIndex: 'address', key: '3', width: 150,ellipsis:true  },
  { title: 'Column 4', dataIndex: 'address', key: '4', width: 150,ellipsis:true  },
  { title: 'Column 5', dataIndex: 'address', key: '5', width: 150,ellipsis:true  },
  { title: 'Column 6', dataIndex: 'address', key: '6', width: 150,ellipsis:true  },
  { title: 'Column 7', dataIndex: 'address', key: '7', width: 150,ellipsis:true  },
  { title: 'Column 8', dataIndex: 'address', key: '8',ellipsis:true  },
  {
    title: 'Action',
    key: 'operation',
    fixed: 'right',
    width: 100,
    slots: { customRender: 'action' },
  },
];

const tableRef = ref();

const data: DataItem[] = [];
for (let i = 0; i < 100000; i++) {
  data.push({
    key: i,
    name: `Edrward ${i}`,
    age: 31,
    address: `London Park no. ${i}`,
  });
}

const scrollTo = () => {
  tableRef.value.scrollTo(1000)
}
