NzTable的tree型数据展示

[jacobearl]

What problem does this feature solve?

现在在处理一些拥有父子关系的数据,比如说资源,常常一个资源下又有很多资源，此时想要使用NzTable里的tree型数据展示，但发现ng-zorro-antd的nzTable在这方面的处理比较复杂,并且例子也不太好理解

What does the proposed API look like?

能否像elementui给表格加的 tree-props属性一样, 也给NzTable添加一个类似的属性，用来支持表格数据中children数据的渲染

<nz-table #nzTable [nzData]="dataList"  [tree-props]="{children: 'children', hasChildren: 'hasChildren'}">
</nz-table>

Translation of this issue:

NzTable type of tree data show

What problem does this feature solve?

Now in the process some of the data have parent-child relationship, such as lower resource, a resource often have a lot of resources at this time want to use NzTable in the tree-type data display, but found ng-zorro-antd of nzTable process in this regard complicated and not very good example of understanding

What does the proposed API look like?

Can elementui like to tree-props property sheet Giga like, add a similar property to NzTable, tabular data used to support the rendering data in children
 ` <Nz-table #nzTable [nzData] = "dataList" [tree-props] = "{children: 'children', hasChildren: 'hasChildren'}"> </ Nz-table> `

nz-table 所有的dom结构都是用户可以自由控制的，也就是不通过config 来控制组件渲染，添加这种api 和目前组件设计是直接冲突的，你可以自行封装 nz-table 使用，事实上绝大部分用户也是这样使用的
