固定td标簽的寬度，table邊框1像素

.increase .increase-table {

margin: 0 auto;

width: 350px;

text-align: center;

vertical-align: middle;

border-collapse:collapse;  不建議用cellspacing=0，會造成2像素，看起來太粗，用collapse，再給border

table-layout: fixed; 固定布局，給table标簽寬度

}

.increase .increase-table td {

width: 56px; 給td寬度

height: 44px;

<table class="increase-table" border="1" bordercolor="#fff" cellpadding="0">

<tbody>

    <tr>

        <td class="left">保險</td>

        <td>1險</td>

        <td>2險</td>

        <td>3險</td>

        <td>4險</td>

    </tr>

</tbody>
