问题 I have a requirement to create a excel sheet in JAVA as below : I am not able to create a row label with multiple columns side by side ( menus and submenus filter ). Instead of displaying the submenu in different column, its coming under the menu column. Below is the piece of code which i have written : XSSFSheet sheet = my_xlsx_workbook.getSheetAt(0); AreaReference a=new AreaReference("A1:G7"); CellReference b=new CellReference("I5"); XSSFPivotTable pivotTable = sheet.createPivotTable(a,b);

问题 I have an Excel sheet that allows users to click on specific cells and attach/embed files. These files are typically .pdf and .jpg format. I've read the Busy Developers guide on how to read embedded files using Apache POI, however I don't think I'm actually reading the correct file because when I go to save file locally or encode then decode for testing, the file says corrupt and will not open. Here is some code: for (PackagePart pPart : workbook.getAllEmbedds()) { InputStream inputStream =

问题 I'm trying to do an exact copy of one paragraph into another (I'm copying a template over to a new document for word-replacement). I'm doing this for paragraphs within a table cell, but I don't believe that is significant. The following code nearly works: for (XWPFParagraph p : cell.getParagraphs()) { XWPFParagraph np = newCell.addParagraph(); np.getCTP().set(p.getCTP()); } The problem is, while np.getCTP().xmlText().equals(p.getCTP().xmlTest() is true, np.getText() is blank while p.getText()

问题 The relevant part of the Controller class: @RequestMapping(value = "/DBCompare/download", method = RequestMethod.GET) public void handleDownloadDBCompareReportGet(HttpServletResponse response, Model model){ try{ reportService.downloadResultsDto(reportDto); } finally{ } } The ReportService in this case only fetches some information from the database, and calls newTableCompare() from the CreateTable class. The following class should create a new Excel table, workbook, ect. import java.io

问题 I've generated a line chart using Apache POI. I need to change the default colors I got in the chart. Can I use RGB codes to define specific colors to each line? My code is as follows. Drawing drawing = sheet4.createDrawingPatriarch(); ClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 1, 1, 17, 22); Chart chart = drawing.createChart(anchor); ChartLegend legend = chart.getOrCreateLegend(); legend.setPosition(LegendPosition.RIGHT); LineChartData data = chart.getChartDataFactory()

问题 I want to delete an entire row from excel, I have tried removeRow : XSSFRow rerow = sheet1.getRow(1); sheet1.removeRow(rerow); and shiftRows : int rowIndex = 1; int lastIntext = sheet1.getLastRowNum(); sheet1.shiftRows(rowIndex+1, lastIntext, -1); But it is deleting only values in row not the entire row. 回答1: Even i faced the same problems but figured after a couple of researches and found There was a bug/or they might have changed the behavior in <version>4.0.0</version> and <version>4.0.1<
