#### 表格行/列合并
表头只支持列合并，使用 column 里的 colSpan 进行设置。
表格支持行/列合并，使用 render 里的单元格属性 colSpan 或者 rowSpan 设值为 0 时，设置的表格不会渲染。

#### colSpan and rowSpan
Table column title supports `colSpan` that set in `column`.
Table cell supports `colSpan` and `rowSpan` that set in render return object. When each of them is set to `0`, the cell will not be rendered.
