1    var trElement = document.createElement("tr");
   2    var tdElement = document.createElement("td");
   3    tdElement.colSpan = 6;
   4    tdElement.innerHTML = "没有在线用户";
   5    trElement.appendChild(tdElement);

   6    var tBody = document.getElementById("mytBodyId");

  7   tBody.appendChild(trElement);

 

第3行，很多人会写成tdElement.colspan = 6;，是无效的。

第2行，很多人会写成trElement.innerHTML = "《td colspan=6》没有在线用户《/td》";，是无效的。

第4行，是没问题的，也可以再创建一个文本节点然后用tdElement.appendChild()添加。

第7行，很多人会写成tBody.innerHTML = "《tr》《td colspan=6》没有在线用户《/td》《/tr》";，是无效的.
