do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

# 扩展功能
在 [poi-tl](https://github.com/Sayi/poi-tl) 的基础上扩展了如下功能：
- 支持渲染`HTML`字符串，插件`HtmlRenderPolicy`的使用方法如下（也可参考[文档](http://deepoove.com/poi-tl/#_%E4%BD%BF%E7%94%A8%E6%8F%92%E4%BB%B6)）
```java
HtmlRenderPolicy htmlRenderPolicy = new HtmlRenderPolicy();
Configure configure = Configure.builder()
.bind("key", htmlRenderPolicy)
.build();
Map<String, Object> data = new HashMap<>();
data.put("key", "<p>Hello <b>world</b>!</p>");
XWPFTemplate.compile("input.docx", configure).render(data).writeToFile("output.docx");
```
`HtmlRenderPolicy`可以通过`HtmlRenderConfig`进行如下设置：
- `globalFont` 全局默认字体（用于归一化处理，而不是用于样式兜底）
- `globalFontSize` 全局默认字号（用于归一化处理，而不是用于样式兜底）
- `showDefaultTableBorderInTableCell` 是否显示嵌套表格的边框（`poi`生成嵌套表格时默认不显示边框，见[#12](https://github.com/draco1023/poi-tl-ext/issues/12)）
- `numberingIndent` 多级列表项缩进长度，默认值360
- `numberingHanging` 列表项悬挂长度，默认值360，CSS样式`list-style-position`为`inside`时该参数无效
- `numberingSpacing` 列表编号与内容之间的间隔类型，`STLevelSuffix.NOTHING`/`STLevelSuffix.SPACE`/`STLevelSuffix.TAB`
自定义`<latex>`标签，允许渲染嵌入在`HTML`中的`LaTeX`，字符串格式可参考[文档](https://www2.ph.ed.ac.uk/snuggletex/documentation/supported-latex.html)。
_目前实现了富文本编辑器可实现的大部分效果，后续继续改进..._
- 支持渲染`MathML`字符串，插件类为`MathMLRenderPolicy`
- 支持渲染`LaTeX`字符串，插件类为`LaTeXRenderPolicy`
## 支持我
如果您觉得这个插件节省了您的时间和精力，或者解决了您的难题，可以考虑支持一下我的工作，感谢！ ⚡⚡⚡
