通过列匹配对两个表进行求和

如何解决通过列匹配对两个表进行求和

我有两个表，第一个是货币和价值，第二个是货币和 x-rate。 通过匹配两个表中的货币列，我想将这些值相乘和求和。

货币	价值
欧元	10
英镑	20
瑞士法郎	30
欧元	40
英镑	50

第二个

货币	x_rate
欧元	1
英镑	1.2
瑞士法郎	1.3

结果应该是：import * as React from 'react'; import { useState } from 'react'; import { Button,View,Text,Image,SafeAreaView,ScrollView,} from 'react-native'; import RadioButtonRN from 'radio-buttons-react-native'; import { Card,Title } from 'react-native-paper'; import Icon from 'react-native-vector-icons/FontAwesome'; import Constants from 'expo-constants'; function App() { const [data,setData] = useState([{ label: 'data 1' },{ label: 'data 2' },]); const [SecondData,setSecondData] = useState([{ label: 'data 5' },{ label: 'data 6' },{ label: 'data 7' },{ label: 'data 8' },]); const keeper = data.map((item) => { < Text > { item.label } < /Text> console.log(item.label) }) return ( < SafeAreaView > < ScrollView showsverticalScrollIndicator > < View style = { { marginTop: Constants.statusBarHeight } } > < Card mode = "outlined" style = { { borderColor: 'blue',padding: 10,backgroundColor: '#ccc',} } > < Card.Content > < Title > SRC PRESIDENT < /Title> < /Card.Content> < RadioButtonRN data = { keeper } selectedBtn = { (e) => console.log(e) } icon = { < Icon name = "stop-circle" size = { 25 } color = "#2c9dd1" / > } /> < /Card> < Card mode = "outlined" style = { { borderColor: 'blue',marginTop: 20,} } > < Card.Content > < Title > GENERAL SECRETARY < /Title> < /Card.Content> < RadioButtonRN data = { SecondData } selectedBtn = { (e) => console.log(e) } icon = { < Icon name = "check-circle" size = { 25 } color = "#2c9dd1" / > } /> < /Card> < /View> < /ScrollView> < /SafeAreaView> ); } export default App;

解决方法

使用数组公式：

=SUMPRODUCT(B2:B6*TRANSPOSE(E2:E4)*(A2:A6=TRANSPOSE(D2:D4)))

编辑后的数组公式按 ctrl + shift + enter 确认

,

=SUMPRODUCT(($B$2:$B$6)*INDEX($E$2:$E$4,MATCH($A$2:$A$6,$D$2:$D$4,0)))

其中 $A$2:$B$6 是第一桌，$D$2:$E$4 是第二桌。
