Grouping columns

#73

实现了基本的表头合并，还需要看看一些特殊情况的处理。

A	B

要考虑这种情况吗，不知道怎么处理。

可以不考虑。

发现 fixed column 也不好处理：

姓名	其它
	年龄	住址

这种情况下如果“姓名”是固定的，左边的 fixed table 的头部生成出来就是这样的：

<thead>
  <tr>
    <th rowspan="2">姓名</th>
  </tr>
</thead>

但是因为只有一行，所以rowspan就会失效。想要rowspan有效，就要补一行：

<thead>
  <tr>
    <th rowspan="2">姓名</th>
    <th>.</th>
  </tr>
  <tr>
    <th>.</th>
  </tr>
</thead>

但是好像没好的办法把这补的部分隐藏起来，把它设为display: none也是会让rowspan失效。

看了下 ag-grid，它的表格是用 div 来实现的，所以比较容易处理这种情况。

如果我没理解错，应该可以通过设置 height 的方式实现？

<thead>
  <tr>
    <th height={100}>姓名</th>
  </tr>
</thead>

[yesmeck]

@benjycui 嗯，用 height 搞定了，我的做法是给<th rowspan="2">加一个.rc-table-rowspan-2的 class。不过这样的问题是 css 需要先定义好，我先定义了 10 个，也就是说rowspan最多只能到 10。

columnsPageSize 已经 deprecated 了还要去支持它吗？不知道打算什么时候移除。

@afc163 @benjycui 如果不需要处理columnsPageSize的话，有空可以 review 下。

ant-design 那边要 PR 到 master 吗？

[afc163]
