ng + zorro angular表格横纵向合并，横向目前是手动，纵向是自动合并，微调后可适配三大框架使用

表格横纵向合并，可以看一下代码编写之前和之后的样式，先上图~~

表格页面文件.html

<h1>正常表格</h1>
<nz-table #colSpanTable [nzData]="table03" nzBordered>
  <tbody>
    <tr *ngFor="let item of table03; index as i">
      <td>{{item.Project01}}</td>
      <td>{{item.Project02}}</td>
      <td>{{item.Project03}}</td>
      <td>{{item.Project04}}</td>
      <td>{{item.Project05}}</td>
    </tr>

  </tbody>
</nz-table>

<h1>经过合并的表格</h1>
<h3>
  注意1： [nzData]="table01"必须为数组类型！！！！否则会报错core.js:6157 ERROR TypeError: object is not iterable (cannot read property
  Symbol(Symbol.iterator))
</h3>
<h3>
  注意2：&lt; th [colspan]="tableCol" &gt;是这样子写
</h3>
<h3>
  注意3：&lt; td [attr.colspan]="tableCol" &gt;是这样子写
  以上两者写法不一致，写的不对会失效
</h3>
<nz-table #colSpanTable [nzData]="table01" nzBordered>
  <thead>
    <tr>
      <th [colspan]="table01[0].arr.length + tableCol">{{table01[0].title}}</th>
    </tr>
    <tr>
      <th [colspan]="tableCol">Project</th>
      <th *ngFor="let item of table01[0].arr; index as i">{{item}}</th>
