语法
BYROW函数的语法有以下参数。
array
一个要用列来分隔的数组。
lambda
一个LAMBDA，将一个行作为单一参数，并计算一个结果。该LAMBDA需要一个单一的参数。
row
阵列中的一行。
备注
在使用这个函数之前，你需要打开allowDynamicArray选项
示例
返回每行数据的最大值
var data = {
values: {
1: { 1: "Examples" },
3: { 1: "Example 1: Returns the maximum value of each row of data" },
4: { 1: "Data:", 5: "Formula:" },
5: { 1: 1, 2: 2, 3: 3, 5: "Result:" },
6: { 1: 4, 2: 5, 3: 6 },
8: { 1: "Example 2: Returns the maximum value of each squared value of an array" },
9: { 1: "Data:", 5: "Formula:" },
10: { 1: 1, 2: 2, 3: 3, 5: "Result:" },
11: { 1: 4, 2: 5, 3: 6 },
},
formulas: {
4: { 6: "FORMULATEXT(G6)" },
5: { 6: "BYROW(B6:D7,LAMBDA(array,MAX(array)))" },
9: { 6: "FORMULATEXT(G11)" },
10: { 6: "BYROW(B11:D12,LAMBDA(array,SUMSQ(array)))" },
