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
