POI獲取excel單元格紅色字體，淡藍色前景色的內容

如果是Microsoft Excel 97-2003 工作表 (.xls)

if(31 == cell.getCellStyle().getFillForegroundColor()) //判斷單元格前景色為淡藍色
if(10 == book.getFontAt(cell.getCellStyle().getFontIndex()).getColor()) //判斷單元格字體顏色為紅色

如果是Microsoft Excel 工作表 (.xlsx)

if(0 == cell.getCellStyle().getFillForegroundColor()) //判斷單元格前景色為淡藍色
if(0 == book.getFontAt(cell.getCellStyle().getFontIndex()).getColor()) //判斷單元格字體顏色為紅色
