设置 ：横屏板式
XWPFDocument doc = new XWPFDocument();CTDocument1 document = doc.getDocument();CTBody body = document.getBody();if (!body.isSetSectPr()) {body.addNewSectPr();}CTSectPr section = body.getSectPr();if (!section.isSetPgSz()) {section.addNewPgSz();}//1. 设置页面大小 当前A4大小CTPageSz pageSize = section.getPgSz();//1.1 必须要设置下面两个参数，否则整个的代码是无效的pageSize.setW(BigInteger.valueOf(16840));pageSize.setH(BigInteger.valueOf(11907));pageSize.setOrient(STPageOrientation.LANDSCAPE);
3.设置excel表格布局方式
//4 表格内容XWPFTable comTable = doc.createTable();//4.1表格宽度为指定宽度：STTblWidth.DXA 1CTTblPr ctTblPr = comTable.getCTTbl().addNewTblPr();CTTblWidth comTableWidth = ctTblPr.addNewTblW();comTableWidth.setType(STTblWidth.DXA);comTableWidth.setW(BigInteger.valueOf(16000));//4.1.2设置布局为固定不便方式CTTblLayoutType ctTblLayoutType = ctTblPr.isSetTblLayout()?ctTblPr.getTblLayout():ctTblPr.addNewTblLayout();ctTblLayoutType.setType(STTblLayoutType.FIXED);

三、工具类使用方式及效果
String titleStr = "标题";String description = "描述";String[] value_columns = {"列1", "列2", "列3","列4","列5","列6","列7","列8"};List<List<String>> dataList = new ArrayList<>();//导出的数据Integer[] colWidths = {600,1700,2200,700,900,1500,7350,1050};//导出的excel宽度excel(扣除边距剩余共16000宽)ParagraphAlignment[] excelAlign = {ParagraphAlignment.CENTER,ParagraphAlignment.LEFT,ParagraphAlignment.LEFT,ParagraphAlignment.CENTER,ParagraphAlignment.CENTER,ParagraphAlignment.LEFT,ParagraphAlignment.LEFT,ParagraphAlignment.CENTER};//设置水平方向downWordTransverse(titleStr,titleStr,description,value_columns,dataList,colWidths,excelAlign,response);
