阿里巴巴EasyExcel自定义表格样式
基于注解方式设置标题栏-------@ExcelProperty /** * 行政区名称 */ @ExcelProperty({"行政区名称","行政区名称"}) @ColumnWidth(9) private String areaName; /** * 疫木处置总重量（公斤） */ @ExcelProperty({"1","疫木处置总体情况","疫木处置总重量（公斤）"}) @ColumnWidth(12) private Double totalWeight; /** * 疫木处置树干重量（公斤） */ @ExcelProperty({"2","疫木处置总体情况","疫木处置树干重量（公斤）"}) @ColumnWidth(14) private Double trunkWeight; /** * 疫木处置枝桠重量（公斤） */ @ExcelProperty({"3","疫木处置总体情况","疫木处置枝桠重量（公斤）"}) @ColumnWidth(14) private Double branchWeight;导出样式
在@ExcelProperty({"","",…,""})中可以放置多个字段名称,有几个双引号代表表格头就有几行，名称相同会自动合并单元格。 设置单元格样式 可以是基于注解方式设置表头格式 @ColumnWidth(12) @HeadStyle(fillBackgroundColor = 9) @HeadFontStyle(bold = false,fontHeightInPoints = 10)也可以是通过代码方式自定义表格头部和内容样式 //内容样式策略 WriteCellStyle contentWriteCellStyle = new WriteCellStyle(); //垂直居中,水平居中 contentWriteCellStyle.setVerticalAlignment(VerticalAlignment.CENTER); contentWriteCellStyle.setHorizontalAlignment(HorizontalAlignment.CENTER); contentWriteCellStyle.setBorderLeft(BorderStyle.THIN); contentWriteCellStyle.setBorderTop(BorderStyle.THIN); contentWriteCellStyle.setBorderRight(BorderStyle.THIN); contentWriteCellStyle.setBorderBottom(BorderStyle.THIN); //设置 自动换行 contentWriteCellStyle.setWrapped(true); // 字体策略 WriteFont contentWriteFont = new WriteFont(); // 字体大小，加粗，字体类型 contentWriteFont.setFontName("宋体"); contentWriteFont.setFontHeightInPoints((short) 10); contentWriteCellStyle.setWriteFont(contentWriteFont); //头部样式策略 WriteCellStyle headWriteCellStyle = new WriteCellStyle(); headWriteCellStyle.setWriteFont(contentWriteFont); // 输出为文件 EasyExcel.write("C:\\Users\\Desktop\\Excel自定义样式.xlsx", WeightCountySummaryDTO.class) .sheet("自定义") .registerWriteHandler(HorizontalCellStyleStrategy(headWriteCellStyle, contentWriteCellStyle)) .relativeHeadRowIndex(1) // 设置表格头从第几行开始 .doWrite(dataList);代码自定义表格的样式优先级高于基于注解定义。也就是说你已经基于注解方式定义了表格样式，但后来你又用代码设置了头部样式，那么导出的表格样式是通过代码设置的样式。 扩展-自动合并连续出现的相同单元格 编写一个实现CellWriteHandler的类 public class ExcelCellMergeStrategy implements CellWriteHandler { // 设置合并相同名称的单元列 private int[] mergeColumnIndex; // 从哪行开始合并 private int mergeRowIndex; public ExcelFillCellMergeStrategy() { } public ExcelFillCellMergeStrategy(int mergeRowIndex, int[] mergeColumnIndex) { this.mergeRowIndex = mergeRowIndex; this.mergeColumnIndex = mergeColumnIndex; } @Override public void beforeCellCreate(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, Row row, Head head, Integer columnIndex, Integer relativeRowIndex, Boolean isHead) { } @Override public void afterCellCreate(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, Cell cell, Head head, Integer relativeRowIndex, Boolean isHead) { } @Override public void afterCellDataConverted(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, CellData cellData, Cell cell, Head head, Integer integer, Boolean aBoolean) { } @Override public void afterCellDispose(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, List list, Cell cell, Head head, Integer integer, Boolean aBoolean) { //当前行 int curRowIndex = cell.getRowIndex(); //当前列 int curColIndex = cell.getColumnIndex(); if (curRowIndex > mergeRowIndex) { for (int i = 0; i |
