<cn>
#### 固定表头
方便一页内展示大量数据。
需要指定 column 的 `width` 属性，否则列头和内容可能不对齐。（建议留一列不设宽度以适应弹性布局）
</cn>

<us>
#### Fixed Header
Display large amounts of data in scrollable view.
> Specify width of columns if header and cell do not align properly.(Leave one column at least without width to fit fluid layout)
</us>
