>> 只有 `<text>`和`<richtext>`组件支持。
* `lines {number}`: 正整数，指定最大文本行数，默认值为0，表示不限制最大行数。如果文本不够长，实际展示行数会小于指定行数。
+* `line-height {length}`：正整数，每行文字高度。`line-height`是 top 至 bottom
的距离。`line-height`与`font-size`没有关系，因为`line-height`被
top 和 bottom 所限制，`font-size` 被 glyph
所解析。`line-height`和`font-size`相等一般会导致文字被截断。

- `text-overflow`:<enum> `clip` | `ellipsis`. This property determines
how overflowed content that is not displayed is signaled to users. It can be
clipped, display an ellipsis.
>> Only support for `<text>` and `<ricthext>`
- `lines`: <number> positive number. This is the max lines of text that
would be displayed, the default value is 0 which means there is no restriction
on text lines. If the text is not enough, the actual number of line may be
shorter than the specified value.
+- `line-height`: <length> The line height of every line in the text.
`line-height` is the space between top and
bottom. There is no
relationship between `line-height` and `font-size`, as `line-height` is
restricted by top and bottom, `font-size` is interpreted by glyph. Usually but
not always, `line-height` and `font-size` with the same value will cause the
text clipped.
