First look at the effect:
When using the Ruoyi framework, I found that the built-in export function cannot export multiple sheets and merged cells, so I made a modification here and hope it can help you. If you use it, give it a thumbs up!
let's go step by step
The idea of the whole program is to return to the download address first, and then download excel according to the download address
One: Return to the download address
First of all, we need the download address of excel, here we jump directly to the exportExcel method, the following is the code part
Among them, list and listyw are the data of two sheets
@GetMapping("/export")
public AjaxResult export(BizGuideFileDto bizGuideFile) {
List<BizGuideFileDto> list=iBizGuideFileService.selectBizGuideFile(bizGuideFile);
List<BizGuideFileDto> listyw=iBizGuideFileService.selectBizGuideFile2(bizGuideFile); ExcelUtilMerge<BizGuideFileDto> bizDSubjectExcelUtil = new ExcelUtilMerge<BizGuideFileDto>(BizGuideFileDto.class);
return AjaxResult.success(bizDSubjectExcelUtil.exportExcel
(list,listyw, "sheet1","sheet2","标题据",list.get(0).getFileTitle()));
}
public AjaxResult exportExcel(List<T> list,List<T> listyw, String sheetName,String sheetName2, String title,String title2)
{
this.init(list,listyw, sheetName,sheetName2, title, title2,Type.EXPORT, Excelyw.Type.EXPORT);
return exportExcel();
}1. How to create multiple sheet pages
Below is the tool class I attached. You can see that in the method init, compared with the source code, there are a few more items with the end number 2, which is the second sheet. It is available when building a workbook, obtaining annotations, and obtaining data export. Related 2, the specific situation can be seen in the code/
The specific logic can be seen step by step from init
2. How to merge cells
exportExcel() ---> writeSheet() ---> fillExcelData(index, row) ---> this.addCell(excel, row, vo, field, column++);
First look at ExcelUtil<T> according to this idea
There are only three lines of code for merging. Here I made a judgment, because there is a for loop outside this method. If I don’t make a judgment, I will report multiple merge errors. Although the result is correct, I feel uncomfortable because of obsessive-compulsive disorder
The logic of merging here starts from the third line, ends at listyw.size()+1 line, starts at column 0, and ends at column 0
if (heBing==true){
CellRangeAddress region = new CellRangeAddress(2, (short)listyw.size()+1, 0, (short)0);
sheet2.addMergedRegion(region);
this.heBing=false;
}3. Custom export fields
Because Ruoyi export can be customized to select the exported fields, so you only need to add annotations to the fields that need to be exported. @Excel is the source code of Ruoyi, which is to obtain the exported fields of the first sheet. @Excelyw is I added it myself to obtain the annotations of the exported fields on another sheet page. The specific logic can be copied from Excel.
