POI中過濾掉帶消除線的文字 （Excel 2003 版）

直接上代碼：

 

HSSFRichTextString richTextString = cell.getRichStringCellValue();
String realString = richTextString.getString();

boolean isCellStrikeOut = false;
HSSFCellStyle cellStyle = cell.getCellStyle();
if (cellStyle != null) {
    HSSFFont font = workbook.getFontAt(cellStyle.getFontIndex());
    if (font.getStrikeout()) {
        isCellStrikeOut = true;
    }
}

if (richTextString.numFormattingRuns() == 0) {
    if (isCellStrikeOut) {
        return "";
    }

    return realString;
} else if (!isCellStrikeOut) {
    StringBuilder sb = new StringBuilder(realString);
    int lastIndex = realString.length();
    for (int i = richTextString.numFormattingRuns() - 1; i >= 0 ; i --) {
        short fontIndex = richTextString.getFontOfFormattingRun(i);
        HSSFFont font = workbook.getFontAt(fontIndex);
        if (font.getStrikeout()) {
            sb.delete(richTextString.getIndexOfFormattingRun(i), lastIndex);
        }
