Hello world!

"); 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``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！ ⚡⚡⚡ ![wechat_sp](https://pub-1085551b511e4719a277177fe3c8f95b.r2.dev/wechat_sp.jpg) ================================================ FILE: build.gradle ================================================ /* * Copyright 2016 - 2021 Draco, https://github.com/draco1023 * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ plugins { id 'java-library' id 'io.github.sgtsilvio.gradle.maven-central-publishing' version '0.4.0' } def getBranchName() { providers.exec { commandLine("git", "branch", "--show-current") }.standardOutput.asText.get().trim() } ext { VERSION_NAME = 'poi-5' == getBranchName()?

今天（21日）0时，位于新疆南部的塔里木油田年油气产量达到3003.12万吨，成为我国油气上产重要战略接替区。

　　位于大北博孜气区的大北902井近日喷出高产气流，今年这里试油的6口井均获40万立方米以上高产。目前，天山南麓还有60多部钻机正在钻进，近两年，塔里木油田超过100口气井获高产，新建天然气产能90亿立方米。

　　
 

　　中石油塔里木油田公司总经理 杨学文：“十三五”期间，塔里木油田大力提升勘探开发力度，已经落实两个万亿方大气区，形成10亿吨级大油气区，为新一轮的油气增储上产奠定了坚实的资源基础。

　　56万平方公里的塔里木盆地是我国陆上最大的含油气盆地，盆地遍布大漠戈壁，油气大多蕴藏在超过6000米的地宫深处，面临超深、超高温、超高压等极限考验，是世界级勘探禁区。油田的科技工作者攻克了一系列世界级难题，探明油气储量26.7亿吨。

创建和编辑页面是不能被 keep-alive 缓存的，因为keep-alive 的 include 目前不支持根据路由来缓存，所以目前都是基于 component name 来进行缓存的。如果你想类似的实现缓存效果，可以使用 localStorage 等浏览器缓存方案。或者不要使用 keep-alive 的 include，直接缓存所有页面。详情见 Document
