Answer 1

在css中使用以下代码

.select {
  margin: 0;
  padding: 0;
}

Answer 2

将margin:0添加到<dl>元素：

* {
  font-family: Segoe UI;
  font-size: 9pt;
}
.select dd,
.select dt,
.select ul {
  margin: 0px;
  padding: 0px;
}
.select dd {
  position: relative;
}
.select a,
.select a:visited {
  color: #000;
  text-decoration: none;
  outline: none;
}
.select dt:hover,
.select dd ul:hover {
  border-color: rgb(128, 128, 128);
}
.select dd ul li a:hover {
  background-color: rgb(112, 146, 190);
  color: #FFF;
}
.select dt {
  background: url(arrow.png) no-repeat scroll right center;
  display: block;
  padding-right: 20px;
  border: 1px solid rgb(170, 170, 170);
  width: 180px;
  overflow: hidden;
}
.select dt span {
  cursor: pointer;
  display: block;
  padding: 4px;
  height: 15px;
}
.select dd ul {
  background: #fff none repeat scroll 0 0;
  border-bottom: 1px solid rgb(170, 170, 170);
  border-left: 1px solid rgb(170, 170, 170);
  border-right: 1px solid rgb(170, 170, 170);
  border-top: 0;
  display: none;
  left: 0px;
  padding: 5px 0px;
  position: absolute;
  top: -1px;
  width: auto;
  min-width: 200px;
  list-style: none;
}
.select dd ul li a {
  padding-left: 10px;
  padding-top: 3px;
  padding-bottom: 3px;
  display: block;
}
.selected {
  background: rgb(195, 195, 195);
}
.header-list,
.header-list:hover {
  padding-left: 3px;
  font-weight: bold;
  font-style: italic;
  cursor: pointer;
}
dl {
  margin: 0;
}

＆＃13;

<table style="border-collapse: collapse;" cellpadding="0" cellspacing="0">
  <tr>
    <td>
      <dl data-val="multiple" class="select">

        </dd>
      </dl>
    </td>
  </tr>

  <tr>
    <td>
