<script>
        var num=;
        var cols=;    //5列
        var rows=(num/);
        var no = ;
        var htmlstr="<table  style='position:absolute;top:9%;left:10%; border-radius:12px;border:10px solid RGB(221,183,132);'>";
        for(i=;i<=rows;i++){
         htmlstr+="<tr>";
         for(j=;j<=cols;j++){
             no=(i*)+j;
          htmlstr+="<td ><div id='player'><div style='width:103px;height:80px;'></div><span style='margin-left:19px;'>"+no+"号玩家</span></div></td>";
