问题 I'm using Apache POI for my app and I want to set columns names instead of "A, B, C..." I use the following code but it adds just data in first row: public void createHeaderRow(HSSFSheet sheet, List<String> headerRowList) { HSSFRow headerRow = sheet.createRow(0); for(int i=0;i<headerRowList.size();i++){ HSSFCell cell = headerRow.createCell((short) i); cell.setCellValue(headerRowList.get(i).toString()); } } So any ideas? 回答1: Bad news: AFAIK excel cannot do anything different than A, B, C.

问题 How can i import a new font to POI API with extensions ttf & otf , without install these fonts into the environment ? Is there a jar that i should update it with the path of the new font ? 回答1: Normally You cannot add fonts... You can think your (office) files just like HTML. Font lives outside the document. You just set the font name, family, etc. Update: However, someone has already tried to do that. Using embedded files, you could add font files. Link: http://apache-poi.1045710.n5.nabble

I receive some excel files that have PDFs embedded in it and i want to extract them and rename them based on the row and column they are in.

The following code snippet lets me extract the embedded PDFs but they are named OleObject[1

问题 I've been banging my head against the wall on this problem for a while now, and I've done my fair share of looking through existing StackOverflow questions that are similar to my predicament, but haven't found a solution that works for me yet. I've got existing code that takes an HttpServletResponse and exports it as an .xls attachment for the user to download. This code is presented here: import java.io.IOException; import javax.faces.context.FacesContext; import javax.servlet.http

问题 I created a word-document with apache-poi (poi-ooxml version 3.15) and now I want to write unit tests for my classes. What is the best way to do that? We're using mockito(2.15.0) in our project. This is one of the classes I'm trying to write test for: @Component public class ProffesionalSumaryService { public void populateDocumentWithProfileSkills(XWPFDocument document, ExportProfileDTO profileData){ XWPFTable antet = document.createTable(); antet.getCTTbl().getTblPr().getTblBorders()
