1.IF的判斷語句，格式爲：
=IF(如果符合這個條件，那麼輸出數值1，否則輸出數值2),如果希望單元格數值爲空，則"".
e.g.1
=IF(COUNTIF('Added Safe&Account'!H285,"default"),"22")
e.g.2 (這裏的兩組""都不能省去)
=IF('Added Safe&Account'!E285="Oracle",'Added Safe&Account'!H285,"")
=IF('Added Safe&Account'!N285="",'Added Safe&Account'!N285,"")
2.等同於IF,ELSE IF,ELSE的語法。AND(值1，值2，值3)用來表示且。
如果同時滿足兩個條件則爲22，否則如果同時滿足另兩個條件則爲1521，如果都不符合則爲空值
e.g.1
=IF(C3="OS","Operating System", IF(C3="NW","Network Device",IF(C3="DB","Database",IF(C3="App","Operating System"))))
e.g.2
=IF(AND('Added Safe&Account'!E285="AIX",'Added Safe&Account'!H285="default"),"22",IF(AND('Added Safe&Account'!E285="Unix_or_Linux",'Added Safe&Account'!H285="default"),"22",IF(AND('Added Safe&Account'!C285="NW",'Added Safe&Account'!G285="Telnet"),"23",IF('Added Safe&Account'!E285="SQL_Server","1433",IF('Added Safe&Account'!E285="Oracle","1521","")))))
3.IF的判斷語句,輸出結果如果要用hyphen連接,則使用&連接。
OR(值1，值2，值3)用來表示或。
=IF(OR('Added Safe&Account'!C285="NW",'Added Safe&Account'!C285="OS",'Added Safe&Account'!C285="App"),'Added Safe&Account'!W285&"-"&'Added Safe&Account'!U285&"-"&'Added Safe&Account'!K285&"-"&'Added Safe&Account'!M285,'Added Safe&Account'!W285&"-"&'Added Safe&Account'!U285&"-"&'Added Safe&Account'!K285&"-"&'Added Safe&Account'!M285&"-"&'Added Safe&Account'!H285)
4.以某字符爲分隔符，來截取字符串字段
參考文檔：http://www.voidcn.com/article/p-okydhuiw-cv.html
Q29=http://www.163.com/sports/Arsenal.html
=TRIM(LEFT(SUBSTITUTE(Q29,":",REPT(" ",LEN(Q29))),LEN(Q29)))
值爲http
WINServerLocal
=TRIM(LEFT(SUBSTITUTE('Added Safe&Account'!U285,"_",REPT(" ",LEN('Added Safe&Account'!U285))),LEN('Added Safe&Account'!U285)))
