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 🙏

wy_col

v1.0.6

Published

表单单列合并计算

Readme

安装

npm install wy_col

这里只能配合elementUI组件库中的Table合并单元格的 span-method 功能使用

使用


import RowD from 'wy_col';

 arraySpanMethod({ rowIndex, columnIndex }) {
      const  Row = new RowD();
      //tableData 表格数据
      //tagList 需要计算合并列对应表头字段名
      //columnIndex 列索引
      //rowIndex 行索引
      const _row = Row.sumRow(tableData, tagArr, columnIndex);
      const _col = _row[rowIndex] == 0 ? 0 : 1;
      return [_row[rowIndex], _col];
    },

该方法就是从左到右,从上到下,计算出需要合并的行数,然后返回,每个元素都会被分别计算,计算当前列上下参数是否一致,如果一致,继续往左挪动一列计算,否则停止,以此类体知道列数为0,仍然一致保持一致说明当前上下两行是需要合并的,返回合并的行数。

举例

               <el-table-column
                prop="name" label="姓名">
                </el-table-column>
                <el-table-column
                prop="age" label="年龄">
                </el-table-column>          

如果上面的例子是一个表的每一列表述,那么需要合并行传入的 tagList 就是:["name", "age"]
