  1.   

    <table border=1 onclick='if(event.srcElement.tagName=="TD")alert("行："+event.srcElement.parentElement.rowIndex+"\n列："+event.srcElement.cellIndex)'>
      <tr>
        <td id=td0>1_1</td><td>1_2</td><td>1_3</td><td>1_4</td>
      </tr>
        <tr>
        <td>2_1</td><td>2_2</td><td>2_3</td><td>2_4</td>
      </tr>
        <tr>
        <td>3_1</td><td>3_2</td><td>3_3</td><td>3_4</td>
      </tr>
        <tr>
        <td>4_1</td><td>4_2</td><td>4_3</td><td>4_4</td>
      </tr></table>
      

  2.   

    <script>document.writeln("<table border=1>")
    for(r=0;r<10;r++)
    {
    document.writeln("<tr>")
    for(c=0;c<10;c++)
    {
    document.writeln("<td onclick='javascript:alert(\"单击坐标("+(c+1)+","+(r+1)+")\")'>&nbsp&nbsp&nbsp</td>");
    }
    document.writeln("</tr>")
    }
    document.write("</table>");</script>
