Javascriptを使ってテーブルを作成する

3行2セルのテーブルを作成するJavaScript関数があります。

自分の関数を使用して以下の表を作成する方法を誰かに教えてもらえますか（私の状況ではこれを実行する必要があります）。

これが私のJavascriptとHTMLコードです。

function tableCreate() {
  //body reference 
  var body = document.getElementsByTagName("body")[0];

  // create elements <table> and a <tbody>
  var tbl = document.createElement("table");
  var tblBody = document.createElement("tbody");

  // cells creation
  for (var j = 0; j <= 2; j++) {
    // table row creation
    var row = document.createElement("tr");

    for (var i = 0; i < 2; i++) {
      // create element <td> and text node 
      //Make text node the contents of <td> element
      // put <td> at end of the table row
      var cell = document.createElement("td");
      var cellText = document.createTextNode("cell is row " + j + ", column " + i);

      cell.appendChild(cellText);
      row.appendChild(cell);
    }

    //row added to end of table body
    tblBody.appendChild(row);
  }

  // append the <tbody> inside the <table>
  tbl.appendChild(tblBody);
  // put <table> in the <body>
  body.appendChild(tbl);
  // tbl border attribute to 
  tbl.setAttribute("border", "2");
}
<table width="100%" border="1">
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td rowspan="2">&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
  </tr>
</table>

これはうまくいくはずです（上記のコードに対するいくつかの変更から）。

function tableCreate() {
  var body = document.getElementsByTagName('body')[0];
  var tbl = document.createElement('table');
  tbl.style.width = '100%';
  tbl.setAttribute('border', '1');
  var tbdy = document.createElement('tbody');
  for (var i = 0; i < 3; i++) {
    var tr = document.createElement('tr');
    for (var j = 0; j < 2; j++) {
      if (i == 2 && j == 1) {
        break
      } else {
        var td = document.createElement('td');
        td.appendChild(document.createTextNode('\u0020'))
        i == 1 && j == 1 ? td.setAttribute('rowSpan', '2') : null;
        tr.appendChild(td)
      }
    }
    tbdy.appendChild(tr);
  }
  tbl.appendChild(tbdy);
  body.appendChild(tbl)
}
tableCreate();

insertRow および insertCell を使用した少し短いコード

function tableCreate(){
    var body = document.body,
        tbl  = document.createElement('table');
    tbl.style.width  = '100px';
    tbl.style.border = '1px solid black';

    for(var i = 0; i < 3; i++){
        var tr = tbl.insertRow();
        for(var j = 0; j < 2; j++){
            if(i == 2 && j == 1){
                break;
            } else {
                var td = tr.insertCell();
                td.appendChild(document.createTextNode('Cell'));
                td.style.border = '1px solid black';
                if(i == 1 && j == 1){
                    td.setAttribute('rowSpan', '2');
                }
            }
        }
    }
    body.appendChild(tbl);
}
tableCreate();

また、これはCSSを使用する代わりにborder属性を設定するなどの「悪い習慣」を使用せず、document.getElementsByTagName('body')[0]の代わりにbodyからdocument.bodyにアクセスします。

私はあなたがこれが参考になることを願っています。

HTML：

<html>
<head>
    <link rel = "stylesheet" href = "test.css">
<body>

</body>
<script src = "test.js"></script>
</head>
</html>

ジャバスクリプト：

var tableString = "<table>",
    body = document.getElementsByTagName('body')[0],
    div = document.createElement('div');

for (row = 1; row < 101; row += 1) {

    tableString += "<tr>";

    for (col = 1; col < 11; col += 1) {

        tableString += "<td>" + "row [" + row + "]" + "col [" + col + "]" + "</td>";
    }
    tableString += "</tr>";
}

tableString += "</table>";
div.innerHTML = tableString;

This is how to loop through a javascript object and put the data into a table.

    <body>
    <script>
    function createTable(objectArray, fields, fieldTitles) {
      let body = document.getElementsByTagName('body')[0];
      let tbl = document.createElement('table');
      let thead = document.createElement('thead');
      let thr = document.createElement('tr');

      for (p in objectArray[0]){
        let th = document.createElement('th');
        th.appendChild(document.createTextNode(p));
        thr.appendChild(th);
        
      }
     
      thead.appendChild(thr);
      tbl.appendChild(thead);

      let tbdy = document.createElement('tbody');
      let tr = document.createElement('tr');
      objectArray.forEach((object) => {
        let n = 0;
        let tr = document.createElement('tr');
        for (p in objectArray[0]){
          var td = document.createElement('td');
          td.appendChild(document.createTextNode(object[p]));
          tr.appendChild(td);
          n++;
        };
        tbdy.appendChild(tr);    
      });
      tbl.appendChild(tbdy);
      body.appendChild(tbl)
      return tbl;
    }

    createTable([
                  {name: 'Banana', price: '3.04'}, // k[0]
                  {name: 'Orange', price: '2.56'},  // k[1]
                  {name: 'Apple', price: '1.45'}
               ])
    </script> </code>

この特定の質問で説明されている問題を解決しないかもしれませんが、オブジェクトの配列からテーブルを作成しようとしている人々には役に立つかもしれません：
function createTable(objectArray, fields, fieldTitles) {
  let body = document.getElementsByTagName('body')[0];
  let tbl = document.createElement('table');
  let thead = document.createElement('thead');
  let thr = document.createElement('tr');
  fieldTitles.forEach((fieldTitle) => {
    let th = document.createElement('th');
    th.appendChild(document.createTextNode(fieldTitle));
    thr.appendChild(th);
  });
  thead.appendChild(thr);
  tbl.appendChild(thead);

  let tbdy = document.createElement('tbody');
  let tr = document.createElement('tr');
  objectArray.forEach((object) => {
    let tr = document.createElement('tr');
    fields.forEach((field) => {
      var td = document.createElement('td');
      td.appendChild(document.createTextNode(object[field]));
      tr.appendChild(td);
    });
    tbdy.appendChild(tr);    
  });
  tbl.appendChild(tbdy);
  body.appendChild(tbl)
  return tbl;
}

createTable([
  {name: 'Banana', price: '3.04'},
  {name: 'Orange', price: '2.56'},
  {name: 'Apple', price: '1.45'}
],
['name', 'price'], ['Name', 'Price']);
