poi通过在word中写入了表格，通过libreoffice转换成PDF后，word中刚才画的表格宽度无限拉伸问题的解决。

一、复现：

poi版本：

   		<poi>3.17</poi><poi-ooxml>3.17</poi-ooxml><poi-ooxml-schemas>3.17</poi-ooxml-schemas><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>${poi}</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-scratchpad</artifactId><version>${poi}</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>${poi-ooxml}</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml-schemas</artifactId><version>${poi-ooxml-schemas}</version></dependency>

1、生成word：

2、通过libreoffice转换成pdf：

二、失败尝试：设置单元格长度宽度，设置表格居中均无效。

三、解决思路：

1、在word的单元格中，打几个空格，空格其实在红色指到的地方，然后转换成PDF后发现没问题了。

2、将成功和失败的文档进行对比：最后发现表格中格式不太一样

①成功的

②失败的

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xml-fragment xmlns:main="http://schemas.openxmlformats.org/wordprocessingml/2006/main"><main:tblPr><main:tblW main:type="auto" main:w="0"/><main:tblBorders><main:top main:val="single"/><main:left main:val="single"/><main:bottom main:val="single"/><main:right main:val="single"/><main:insideH main:val="single"/><main:insideV main:val="single"/></main:tblBorders></main:tblPr><main:tr><main:tc><main:p/></main:tc></main:tr></xml-fragment>

四、解决方案：设置一下样式，自己画的table放入如下方法

    private static void setTableStyle(XWPFTable table) {// 获取表格的底层 CTTbl 对象CTTbl ctTbl = table.getCTTbl();// 获取或创建表格属性 (tblPr)CTTblPr tblPr = ctTbl.getTblPr();if (tblPr == null) {tblPr = ctTbl.addNewTblPr();}// 获取或创建表格宽度属性 (tblW)CTTblWidth tblWidth = tblPr.getTblW();if (tblWidth == null) {tblWidth = tblPr.addNewTblW();}// 设置表格宽度的类型为 "auto"tblWidth.setType(STTblWidth.AUTO);// 设置宽度为 0，因为当 type="auto" 时，宽度会根据内容自动调整tblWidth.setW(BigInteger.ZERO);// 设置表格网格CTTblGrid tblGrid = ctTbl.getTblGrid();if (tblGrid == null) {tblGrid = ctTbl.addNewTblGrid();CTTblGridCol ctTblGridCol = tblGrid.addNewGridCol();ctTblGridCol.setW(BigInteger.valueOf(9000));}}

五、效果：表格拉宽了。（居中代码就从其他地方抄一下吧，文章很多的）
