Créer un tableau en utilisant Javascript

J'ai une fonction JavaScript qui crée un tableau avec 3 rangées et 2 cellules.

Quelqu'un peut-il me dire comment créer le tableau ci-dessous à l'aide de ma fonction (j'ai besoin de le faire pour ma situation) ?

Voici mon code javascript et html donné ci-dessous :

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>

J'ai écrit une version qui peut analyser dynamiquement une liste d'objets pour créer le tableau sous forme de chaîne. Je l'ai divisé en trois fonctions pour écrire les colonnes d'en-tête, les lignes du corps et assembler le tout. J'ai exporté le tableau sous forme de chaîne pour l'utiliser sur un serveur. Mon code utilise chaînes de modèles pour garder les choses élégantes.

Si vous voulez ajouter du style (comme bootstrap), vous pouvez le faire en ajoutant plus de html à HEAD_PREFIX y HEAD_SUFFIX .

// helper functions
const TABLE_PREFIX = '<div><table class="tg">';
const TABLE_SUFFIX = '</table></div>';
const TABLE_HEAD_PREFIX = '<thead><tr>';
const TABLE_HEAD_SUFFIX = '</tr></thead>';
const TABLE_BODY_PREFIX = '<tbody><tr>';
const TABLE_BODY_SUFFIX = '</tr></tbody>';

function generateTableHead(cols) {
  return `
    ${TABLE_HEAD_PREFIX}
      <td>#</td>
    ${cols.map((col) => `<td>${col}</td>`).join('')}
    ${TABLE_HEAD_SUFFIX}`;
}

function generateTableBody(cols, data) {
  return `
    ${TABLE_BODY_PREFIX}
    ${data.map((object, index) => `
        <tr><td>${index}</td>
        ${cols.map((col) => `<td>${object[col]}</td>`).join('')}
      </tr>`).join('')}
    ${TABLE_BODY_SUFFIX}`;
}

/**
 * generate an html table from an array of objects with the same values
 *
 * @param {array<string>} cols array of object columns used in order of columns on table
 * @param {array<object>} data array of objects containing data in a single depth
 */
function generateTable(data, defaultCols = false) {
  let cols = defaultCols;
  if (!cols) cols = Object.keys(data[0]); // auto generate columns if not defined
  return `
    ${TABLE_PREFIX}
    ${generateTableHead(cols)}
    ${generateTableBody(cols, data)}
    ${TABLE_SUFFIX}`;
}

Voici un exemple d'utilisation :

const mountains = [
  { height: 200, name: "Mt. Mountain" },
  { height: 323, name: "Old Broken Top"},
]
const htmlTableString = generateTable(mountains );

Voici un exemple de dessin d'un tableau à l'aide de raphael.js. Nous pouvons dessiner des tableaux directement sur le canevas du navigateur en utilisant Raphael.js. Raphael.js est une bibliothèque javascript conçue spécifiquement pour les artistes et les graphistes.

<!DOCTYPE html>
<html>

    <head>
    </head>
    <body>
        <div id='panel'></div>
    </body>
    <script src="http://cdnjs.cloudflare.com/ajax/libs/raphael/2.1.0/raphael-min.js"> </script>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

<script>    
paper = new Raphael(0,0,500,500);// width:500px, height:500px

var x = 100;
var y = 50;
var height = 50
var width = 100;

WriteTableRow(x,y,width*2,height,paper,"TOP Title");// draw a table header as merged cell
y= y+height;
WriteTableRow(x,y,width,height,paper,"Score,Player");// draw table header as individual cells
y= y+height;
for (i=1;i<=4;i++)
{
var k;
k = Math.floor(Math.random() * (10 + 1 - 5) + 5);//prepare table contents as random data
WriteTableRow(x,y,width,height,paper,i+","+ k + "");// draw a row
y= y+height;
}

function WriteTableRow(x,y,width,height,paper,TDdata)
{ // width:cell width, height:cell height, paper: canvas, TDdata: texts for a row. Separated each cell content with a comma.

    var TD = TDdata.split(",");
    for (j=0;j<TD.length;j++)
    {
        var rect = paper.rect(x,y,width,height).attr({"fill":"white","stroke":"red"});// draw outline
        paper.text(x+width/2, y+height/2, TD[j]) ;// draw cell text
        x = x + width;
    }
}

</script>
