我正在尝试使用Apache poi dataformatter将数字2852196格式化为$ 2,852,196。
NumberFormat numberFormat = NumberFormat.getCurrencyInstance();
dataFormatter.addFormat("($#,##0_);($#,##0)", numberFormat);
//after adding the above format, i see this format @ index 0, so i have taken 0 in the next line
String formatCellValue = dataFormatter.formatRawCellContents((Long) cols.get(jj).getValue(), 0, "($#,##0_);($#,##0)");
但输出的结果是USD2,852,196。 我遗漏了一些东西或使用了错误的方法。
- 感谢。

此方法更改列数组中的所有元素
您将致电:
protected final static int TYPE_PORCENTAJE = 3;
setTypeColumn(sheet, Arrays.asList(19, 20, 21), TYPE_PORCENTAJE, null);
protected void setTypeColumn(Sheet sheet, List<Integer> columns, int type, Integer format) {
CellType cellType = CellType.STRING;
CellStyle style = sheet.getWorkbook().createCellStyle();
CreationHelper createHelper = sheet.getWorkbook().getCreationHelper();
switch (type) {
case TYPE_NUMBER:
style.setDataFormat(sheet.getWorkbook().createDataFormat().getFormat(BuiltinFormats.getBuiltinFormat(1)));
break;
case TYPE_MONEY:
style.setDataFormat(
sheet.getWorkbook().createDataFormat().getFormat(BuiltinFormats.getBuiltinFormat(format)));
break;
case TYPE_DATE:
style.setDataFormat(createHelper.createDataFormat().getFormat("yyyy-mm-dd"));
break;
case TYPE_PORCENTAJE:
style.setDataFormat(sheet.getWorkbook().createDataFormat().getFormat(BuiltinFormats.getBuiltinFormat(0xa)));
break;
case TYPE_CUSTOM:
style.setDataFormat(
sheet.getWorkbook().createDataFormat().getFormat(BuiltinFormats.getBuiltinFormat(format)));
break;
case TYPE_TEXT:
style.setDataFormat((short) BuiltinFormats.getBuiltinFormat("text"));
break;
default:
break;
}
cellType = CellType.NUMERIC;
final int lastRow = sheet.getLastRowNum();
for (int i = 1; i <= lastRow; i++) {
for (int j = 0; j < columns.size(); j++) {
Cell cell = sheet.getRow(i).getCell(columns.get(j));
String value = null;
if (type == TYPE_TEXT) {
value = cell.getStringCellValue();
}
cell.setCellType(cellType);
cell.setCellStyle(style);
if (type == TYPE_PORCENTAJE) {
cell.setCellValue(cell.getNumericCellValue() / 100);
}
if (type == TYPE_TEXT) {
style.setWrapText(true);
cell.setCellStyle(style);
cell.setCellValue(value);
}
}
}
}
