做爲一個搞編程開發的朋友,千萬不要告訴朋友親戚,你是幹這個的.
不然你就會遇到很多這樣的問題(當然我們都很樂於助人的,可愛的程序員):
我的電腦怎麼沒有聲音了,又或者是我的電腦怎麼沒有顯示了,又或者是下面這樣的.
需求:
a.統計excel表中,每個sheet總,每個項目的費時
a.1:每個sheet中,可能有不同的項目,或者相同的項目
a.2:每個sheet中的項目,又分爲不同類型的項目(不同類型,主要區別于格式不同,然後去判斷是否有重複時得按,sheet,然後類型來區分)
b.將統計的結果,按不同類型的格式,產生一個"彙總"sheet
代碼(POI操作包括,上下合併單元格,左右合併單元格,設置單元格基本格式,寫入公式簡單操作,做個備份記錄學習用):
