问题 I've created this code and The PoiReadExcelFile class will read in the 'poi-test.xls' file into an HSSFWorkbook object. The 'POI Worksheet' will then be read into an HSSFWorksheet object, and then the values within the A1, B1, C1, and D1 cells will be read and displayed to standard output. import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.util.Date; import org.apache.poi.hssf.usermodel.HSSFCell; import org.apache.poi.hssf.usermodel

问题 I have an XSSFSheet with images at the end of my used rows. When adding a new row, I would like to shift all images one row down. I have found this similar question about moving charts, and have tried to use the part of the answer that does the actual moving of the charts, because It looked like it would work for images as well. java.util.List<CTTwoCellAnchor> drawingAnchors = ((XSSFDrawing)sheet.getDrawingPatriarch()).getCTDrawing().getTwoCellAnchorList(); for (CTTwoCellAnchor drawingAnchor

问题 I am using Apache POI to read Excel file(.xlsx) and validate its contents. We are having a date field in excel whcih should be in format MM/dd/yyyy. Suppose if the date fild has two values as follows, 1) 04/24/2014 2) 04242014 I have to accept the first one and reject the second. Since excel stores both these values in integer format, I am not able to differentiate them. Please suggest if you have any idea about how to solve this. 回答1: Apache POI allows to check data format of the cell with:

问题 I am using the NPOI framework to generate a 97/2003 Excel workbook. I need to set a page break every 44 rows and from the example provided in the framework download, the code to do this is: sheet.SetRowBreak(int row) I can verify these are setting a collection of row integers but when opening the document and viewing the Page Break preview, there is but a single page that encompasses the entire worksheet. Sample Code below: for(int rowCount = 0; rowCount < MaxRows; rowCount += 44) { worksheet

Or could I use any other libraries, may be docx4j? UPD: Template docx files with tags are created by end users with MS Word and looks like:

问题 I'm looking for a solution capable of producing a result as close to the original as possible, such as this example, which converts .doc rather than .ppt files. It should, ideally, take in a FileInputStream and output a String with the desired html code. I've come across this question, which posts code very similar to that on the Apache POI website, however it converts to an image and I've been unable to re-purpose it. Otherwise, there seems to be next to no code out there to do this. EDIT: I
