问题 I have written a Java program to read an Excel file cell-by-cell using POI API. The setting of the currency is done explicitly using the MS Excel - "Format Cell" option. However, is there any way in which I can recognize the currency that has been applied to the cell using POI? So far, I have tried using getCellStyle().getDataFormat() and it returns a unique number. However, the problem is that it is based on the cell style, and can change with a change in the cell formatting(font, size, etc.

问题 I am trying to get custom colours to work in Apache POI but I got into a small problem. So far I have been using IndexedColors , but as a palette, it is pretty drab. Thus using an RGB format for colour selection would help me to make my spreadsheets look much better. I have been using this question's answer, as it solves my problem theoretically. However, I am facing a very silly problem that I do not really know how to solve. The error I receive is: The method setFillForegroundColor(short)

问题 I am using POI XSSF API and I would like to transpose a sheet. how can I do that? Thanks. 回答1: Transpose, as in swap A2 with B1 and A3 with C1 (so columns become rows)? If so, there's nothing built in, so you'd need to do a little bit of coding yourself. You'd likely want to grab a pair of cells, save the contents of one (value and style), copy the second to the first, then overwrite the second. See the quick guide if you're not sure on all the reading/writing parts. 回答2: I was looking for
