* Convert java DateFormat patterns into Excel custom number formats. | |
* For example, to format a date in excel using the "dd MMMM, yyyy" pattern and Japanese | |
* locale, use the following code: | |
* | |
* <pre><code> | |
* // returns "[$-0411]dd MMMM, yyyy;@" where the [$-0411] prefix tells Excel to use the Japanese locale | |
* String excelFormatPattern = DateFormatConverter.convert(Locale.JAPANESE, "dd MMMM, yyyy"); | |
* | |
* CellStyle cellStyle = workbook.createCellStyle(); | |
* | |
* DataFormat poiFormat = workbook.createDataFormat(); | |
* cellStyle.setDataFormat(poiFormat.getFormat(excelFormatPattern)); | |
* cell.setCellValue(new Date()); | |
* cell.setCellStyle(cellStyle); // formats date as '2012\u5e743\u670817\u65e5' | |
* </code></pre> | |

* TODO Generalise this for all Excel format strings | |
