如何将这三个数组对齐为行和列。每个第一项都包含相同的in_id，我想把它放在一行和一列

预期输出：

[{80: ["PTP-1","09+75","112D"]]

类似的东西

如何使用 underscorejs 实现

【问题讨论】：

能否包含预期的输出？
好的，我更新我的问题。谢谢
81、82和83呢？
应该被附加。如果第一个数组的长度与第二个数组的长度不同，则应应用空值
请在问题中也包含这一点。在问题明确之前，大多数人将无法更好地帮助您。

【解决方案1】：

由于 id 似乎以相同的顺序出现在三个数组中的每一个中，所以很简单

_.map(_.zip(array1, array2, array3), function(row) {
    var o = {};
    o[row[0].in_id] = _.pluck(row, "ic_value1");
    return o;
});
