Preface

I just needed this function at work some time ago, but I couldn’t find it perfectly after searching a lot, so here I will introduce it myself I made a method to fix the table header, mainly using translate in css3 and a small piece of js code. Let’s take a look below.

详解利用css3 translate完美实现表头固定效果示例

It feels very harmonious, and there are few codes. The disadvantage is IE9 and below do not support the translate attribute, but now there is not much to test for compatibility below IE9. When doing front-end, you will inevitably be constrained by taking into account lower version browsers. . . .

Let’s take a look at the code

HTML

<p class="box">
    <table>
        <thead>
            <tr>
                <th>1</th>
                <th>2</th>
                <th>3</th>
                <th>4</th>
                <th>5</th>
                <th>6</th>
                <th>7</th>
                <th>8</th>
                <th>9</th>
                <th>10</th>
                <th>11</th>
                <th>12</th>
                <th>13</th>
