## 导入依赖 ##

<dependency>
                <groupId>org.apache.poi</groupId>
                <artifactId>poi-scratchpad</artifactId>
                <version>3.17</version>
            </dependency>

## 使用poi生成段落 ##

private XWPFRun setCustomizeOptionParagraph(Integer indentationLeft, ParagraphAlignment align) { 
            XWPFParagraph nestOptionParagraph = document.createParagraph();
            // 缩进
            nestOptionParagraph.setIndentationLeft(indentationLeft);
            // 文本水平居中
            nestOptionParagraph.setAlignment(align);
            // 文本垂直居中
            nestOptionParagraph.setVerticalAlignment(TextAlignment.CENTER);
            XWPFRun nestOptionRun = nestOptionParagraph.createRun();
            nestOptionRun.setFontFamily("宋体");
            nestOptionRun.setColor("000000");
            nestOptionRun.setFontSize(9);
            // 字体加粗
             nestOptionRun.setBold(true);
            //回车换行
            nestOptionRun.addCarriageReturn();
            return nestOptionRun;
        }

## poi 在word中生成表格 ##

### 1.生成表格对象 ###

private XWPFTable setTableWidth(Integer width, Integer rows, Integer cols) { 
            //基本信息表格
            XWPFTable infoTable = document.createTable(rows, cols);
            //设置表格宽度
            CTTblWidth infoTableWidth = infoTable.getCTTbl().addNewTblPr().addNewTblW();
            // 设置为自定义表格宽度
            infoTableWidth.setType(STTblWidth.DXA);
            infoTableWidth.setW(BigInteger.valueOf(width));
            return infoTable;
        }

### 2.设置表格边框 ###

private void setTableBorder(XWPFTable infoTable) { 
         	CTTbl ctTbl = infoTable.getCTTbl();
            //设置边框
            CTTblBorders borders = ctTbl.getTblPr().addNewTblBorders();
            String borderColor = "000000";
            CTBorder lBorder = borders.addNewLeft();
            //线条类型
            lBorder.setVal(STBorder.DOT_DOT_DASH);
            // 线条大小
            lBorder.setSz(new BigInteger("1"));
            // 边框颜色
            lBorder.setColor(borderColor);
    
            CTBorder rBorder = borders.addNewRight();
            rBorder.setVal(STBorder.DOT_DOT_DASH);
            rBorder.setSz(new BigInteger("1"));
            rBorder.setColor(borderColor);
    
            CTBorder tBorder = borders.addNewTop();
            tBorder.setVal(STBorder.DOT_DOT_DASH);
            tBorder.setSz(new BigInteger("1"));
            tBorder.setColor(borderColor);
    
            CTBorder bBorder = borders.addNewBottom();
            bBorder.setVal(STBorder.DOT_DOT_DASH);
            bBorder.setSz(new BigInteger("1"));
            bBorder.setColor(borderColor);
    
        }

### 3. 设置表格内文本 ###

private void setCustomizeTableParagraph(XWPFTableCell cell, String text, TextAlignment valign, ParagraphAlignment align) { 
            CTP ctp = CTP.Factory.newInstance();
            XWPFParagraph p = new XWPFParagraph(ctp, cell);
            p.setAlignment(align);
            p.setVerticalAlignment(valign);
            XWPFRun run = p.createRun();
            run.setText(text);
            run.setFontSize(9);
            run.setColor("000000");
            run.setFontFamily("宋体");
            cell.setParagraph(p);
        }

### 4.设置行高 ###

infoTable.getRow(0).setHeight(2800);

#### 5.设置单元格背景色 ####

infoTableRow.getCell(0).setColor(gray);

#### 6.合并单元格 ####

private void setMergeCell(int row, int cellIndex, XWPFTableCell cell) { 
        // 合并列
            if (row == 0) { 
                if (cellIndex == 1) { 
                    //设置合并开始点
                    cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.RESTART);
                } else { 
                    // 设置合并结束点
                    cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.CONTINUE);
                }
            }
    
            //合并行
            if (cellIndex == 0) { 
                if (row == 0) { 
                    cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.RESTART);
                }
                if (row == 1) { 
                    cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.CONTINUE);
                }
                // 设置合并单元格后文本居中
                cell.setVerticalAlignment(XWPFTableCell.XWPFVertAlign.CENTER);
            }
        }

#### 7.设置单元格宽度 ####

CTTcPr tcpr = cell.getCTTc().addNewTcPr();
            CTTblWidth cellw = tcpr.addNewTcW();
            cellw.setType(STTblWidth.DXA);
            cellw.setW(BigInteger.valueOf(cellWidth));
