问题 If I've got an list of parameters 'x,y,z' that aren't sorted, is there a straightforward way to write them to particular cells in an excel document created with POI, as though the first two parameters are X and Y coordinates? For example, I have rows like: 10,4,100 Is it possible to write the value '100' in the cell at the 10th row, 4th column? Looking at the documentation, it looks straightforward to iterate values into the next row, but I can't see any way of creating a fixed number of rows

问题 I am creating a script for export document as excel. How to have cell value like " Name: Mark DOB: 11-11-2014" by merging few cells? 回答1: What you need to do is create a RichTextString for your cell. That's the way of applying different formatting / styles to different parts of the same cell for display in Excel You'll want to review the POI "Working With Rich Text" example for more on how to use it, but broadly it'll be something like Cell cell = row.createCell(1); RichTextString rt = new

Creating a new cell, copies previous cell's style in Apache POI..?

由 天涯浪子 提交于 2019-12-07 07:57:18
问题 In my java class I am declaring cell like: HSSFCell cell = null; And I am using this cell in many places to create a cell and set values, styles.

When we parse Excel we have to use tab as a delimiter. Is it possible? If yes then why Apache has come up with such a complicated framework. I am puzzled. Can someone help me? 回答1: CSV is a text format, so it can be parsed using the
