我有这样的表:
+================================+==================+===========+=======+
+ + the amount of fruit that has + +
+ Fruits +==================+===========+ Total +
+ + John + Alexa + +
+================================+==================+===========+=======+
+ Apple + 5 + 3 + 8 +
+================================+==================+===========+=======+
+ Grape + 15 + 10 + 25 +
+================================+==================+===========+=======+
+ Total Fruits + 20 + 13 + 33 +
+================================+==================+===========+=======+
在Javascript中如何SUM
在行值中表(SUM in Total Fruits from sum the john apple and grape)
?
如果我的解释无法理解,我很抱歉,你可以再问我,谢谢
