Interesting, but the JavaScript examples hurt:

    let table = [
      ['one','two','three'],
      ['four','five','six']
    ];
    let b = document.body;
    let t = document.createElement('table');
    b.appendChild(t);
    table.forEach((row,ri) => {
      let r = t.insertRow(ri);
      row.forEach((l,i) => {
        let c = r.insertCell(i);
        c.innerText = l;  
      })
    });

Use full words for variable names!
