问题 I am trying to use the xlsx package to fill a spreadsheet with information from an external file. Up until now, I have used addDataFrame() to put information into the spreadsheet, and everything about it that I have tried has been successful (fonts, colors, borders, etc.) The issue now is that I need to have a column of hyperlinks, and to do that I need to get or create the specific cells (I'm not sure which, and both give the same error). The following code: library(xlsx) wb = createWorkbook

问题 Hi I am using apache poi to generate excel files. I am using XSSFWorkbook format. I am trying to make focus on the first cell of the generated excel file.

问题 I can read or write word document in Java using Apache POI or docx4j. But I cant find any references to create or update table of contents in a Word file. Is there any other API can support TOC in Java? Or, is it possible in Apache POI or docx4j to have options to create or update TOC? 回答1: There's a cleaner way for this too. You just need to open a empty docx which will act as a template. Add some sample text into it with the style that you want to include and then this piece of code will

问题 I know there's many same questions on stackoverflow, but it seems that I can't see any possible solution for reading the content of xlsx. What I have try: I have try to put the whole Apache POI library to an android application and try to read the xlsx file. However, the problem is that the Apache POI library is too heavy to put into an android application. An error message shows that the Dalvik VM cannot execute an app with more than 65536 methods. It there any way to read the content of the

问题 Hi I have 1000 encrypted workbooks which I would like to decrypt by providing a pwd. I could not find a decrypt method under apache poi or python's xlrd module. Does anyone know a library which could handle this ( wbc.decrypt(pwd) ). I would prefer a lib i could you use from a unix box. Thanks 回答1: Use the COM bindings to call the Unprotect method. import win32com.client excel = win32com.client.Dispatch('Excel.Application') workbook = excel.Workbooks.open(r'c:\mybook.xls', 'password')

问题 I have a ms-word document (MS-Office 2003; non-xml). Within this document there is a string associated with a bookmark. Furthermore, the word document contains word-macros. My goal is to read the document with java, replace the string associated with the bookmark, and save the document back to word format. My first approach was using Apache POI HWPF: HWPFDocument doc = new HWPFDocument(new FileInputStream("Test.doc")); doc.write(new FileOutputStream("Test_generated.doc")); The problem with

问题 Does someone knows what is the meaning and unit of x and y in Office Open XML wrapPolygon ? The documentation states: "Specifies a coordinate on the x-axis. The origin point for this coordinate shall be specified by the parent XML element. ...The possible values for this attribute are defined by the ST_Coordinate simple type (§ 5.1.12.16)." That sounds like it should be describing a polygon starting at x =0 and y =0 in top left point of the picture. And the unit would be EMU . But this cannot
