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 🙏

依赖

用法

import {WorkbookDef, SheetDef, ColumnDef, ColumnEnum} from 'xlsxio'

const wb = new WorkbookDef([
  new SheetDef('Sheet1', [
    new ColumnDef('列名称', '字段名称', {
      help: '此列的帮助信息',
      headerStyle: {
        width: 20,
        size: 12
      }
    }),
  ], {
    help: '此表的帮助信息'
  }),
  new SheetDef('Sheet2', [
    new ColumnDef('列名称', '字段名称', {
      help: '此列的帮助信息'
    }),
  ])
])

// 从文件导入数据, file 是通过 <input type="file" /> 选择的文件
const data = wb.read(file)
// 将数据写入文件,可以通过第二个参数指定文件名,指定时会下载文件
const blobData = wb.write([{
  name: 'Sheet1',
  rows: []
}, {
  name: 'Sheet2',
  rows: []
}])
// 下载导入模板文件
// true 表示需要输出帮助信息
wb.write([], '模板文件名', true)

rows 是表格的数据集合。每行的数据可以是与 ColumnDef 对应的 object,也可以是一个简单 array

详细用法见 src/App.vue

API

  • WorkbookDef 工作薄定义对象,这是操作 Excel 的入口
  • SheetDef 表定义对象,一个工作薄中可以包含多个表
  • ColumnDef 列定义对象,一个表中可以包含多个列

后记

为了让单元格注释能自动适应内容大小,对原始的输出进行了处理:

文件 xl/drawings/vmlDrawing2.vml

<v:textbox><div style="text-align:left;"></div></v:textbox>
// 替换为
<v:textbox style="mso-fit-shape-to-text:t"><div style="text-align:left;"></div></v:textbox>

需要关注 PR #1933,若其被合并, 则需要移除此操作,并在输出注释参数上添加 autoShape: true
