我是网络脚本的新手,我不明白为什么top在下面的代码中给出了两次:

<div id='divErrorDictionarySearch' style='position:absolute;top:10px;height:100%;width:90%;left:20px;top:20px;'>

为什么给它两次？将使用哪个值？

我正在尝试创建一个表,其中每行具有固定的高度,但是当达到特定高度时,会出现滚动条.

该表的代码是:

<div style="postion: relative; left: 100px; height: 100px; width: 450px; overflow-y: auto">

    <table id="dataTable" style="position: absolute; left: 100px; height: 100px; width: 400px">
        <tr>
            <th>Data Source </th>
            <th>File Type </th>
            <th>FIles</th>
        </tr>
        <tr>
            <td>EDI DATA </td>
            <td>
                <select>
                    <option>ALL </option>
                    <option>CSV</option>
                    <option>xls </option>
                    <option>sap</option>
                </select>
            </td>
            <td>
                <ul>
                    <li>EDI_Aug.csv</li>
                    <li>EDI_Aug.xls </li>
                    <li>EDI_Aug.xls </li>
                </ul>
            </td>
        </tr>
        <tr>
            <td>RECEIPT DATA </td>
            <td>
                <select>
                    <option>CSV</option>
                    <option>xls </option>
