将TxtBody.value换成TableID.innerHTML就可以

Answer 1

<input type="button" value="Save" onclick="SaveText()">
<script>
function SaveText()
{
    //取得id=tb的表格的HTML代码.
    var strHTML = tb.outerHTML;
    var winSave = window.open();
    winSave.document.open ("text/html","gb2312");
    winSave.document.write (strHTML);
    winSave.document.execCommand ("SaveAs",true,"table.htm");
    winSave.close();
}
</script>
<table id="tb">
<tr><td>tttttttt</td></tr>
<tr><td>tttttttt</td></tr>
