javascript - 将嵌套数组转换为对象数组问题

Question

我正在尝试将此嵌套数组数据转换为对象数组。这是数据。

  const tableData = [
    ["first_name", "last_name", "city", "state"],
    ["June", "Gregory", "Hammond", "IN"],
    ["James", "Wynn", "Gary", "IN"],
    ["Craig", "Norman", "Schererville", "IN"]
  ]

输出应该是这样的

[
  { first_name : "June", last_name : "Gregory", city: "Hammond", state : "IN" },
  { first_name : "James", last_name : "Wynn", city: "Gary", state : "IN" },
  { first_name : "Craig", last_name : "Norman", city: "Schererville", state : "IN" }
]

这是我的代码。

    function convertTable(table_data) {
var result = []
var key, value
for (var i=0; i<table_data.length; i++) {
  var employee = {}
  for (var j=0; j<table_data[i].length; j++) {
    key = table_data[i][j][0]
    value = table_data[i][j][1]
    employee[key] = value
   }
   result.push(employee)
  }
  return result
 }

  var input = [
    ["first_name", "last_name", "city", "state"],
    ["June", "Gregory", "Hammond", "IN"],
    ["James", "Wynn", "Gary", "IN"],
    ["Craig", "Norman", "Schererville", "IN"]
  ]

console.log(convertTable(input));

解决方案是打印单词的第一个字母而不是整个单词。我很难理解为什么。我问是否有任何评论者可以逐行发表评论，以帮助我理解这个程序。我是在研究类似问题的帮助下写的，但仍然很难理解。我一直在 w3schools、MDN 上阅读有关 Javascript 的内容，并观看 Youtube 上的解释视频。任何其他帮助将不胜感激，谢谢。

试试这个，

你只是放错了一些索引，但一切都很好。只需与您的功能相匹配，您就可以轻松找到您错过的地方。

  const tableData = [
    ["first_name", "last_name", "city", "state"],
    ["June", "Gregory", "Hammond", "IN"],
    ["James", "Wynn", "Gary", "IN"],
    ["Craig", "Norman", "Schererville", "IN"]
  ]


    function convertTable(table_data) {
var result = []
var key, value
for (var i=1; i<table_data.length; i++) {
  var employee = {}
  for (var j=0; j<table_data[i].length; j++) {
    key = table_data[0][j]
    value = table_data[i][j]
    employee[key] = value
   }
   result.push(employee)
  }
  return result
 }

  var input = [
    ["first_name", "last_name", "city", "state"],
    ["June", "Gregory", "Hammond", "IN"],
    ["James", "Wynn", "Gary", "IN"],
    ["Craig", "Norman", "Schererville", "IN"]
  ]

console.log(convertTable(input));

  { first_name : "June", last_name : "Gregory", city: "Hammond", state : "IN" },
  { first_name : "James", last_name : "Wynn", city: "Gary", state : "IN" },
  { first_name : "Craig", last_name : "Norman", city: "Schererville", state : "IN" }
] */
