修复了 header 可滚动表 header 和 tbody 不匹配的问题

Question

你可以在

中看到我的html代码

jsfiddle

它提供了一个固定标题的可滚动表格。 thead 和 tbody 的列之间存在轻微的不匹配。我该如何解决？

我需要将 thead 和 tbody 列的边界放在同一位置。

HTML：

<div id="tableContainer" class="tableContainer" style="margin: 0 auto;">
    <table class="scrollTable" cellpadding="0" cellspacing="0" width="100%" border="0">
        <thead class="fixedHeader">
            <tr class="alternateRow">
                <th>File</th>
                <th>Line</th>
                <th>Function</th>
                <th>Value</th>
                <th>Message</th>
            </tr>
        </thead>
        <tbody class="scrollContent">
            <tr class="alternateRow">
                <td>test.cpp</td>
                <td>72</td>
                <td>remove_items_states</td>
                <td>0.000000</td>
                <td>state_flag</td>
            </tr>
                    <tr class="alternateRow">
                <td>test.cpp</td>
                <td>72</td>
                <td>remove_items_states</td>
                <td>0.159990</td>
                <td>state_flag</td>
            </tr>
            <tr class="alternateRow">
                <td>test.cpp</td>
                <td>72</td>
                <td>remove_items_states</td>
                <td>0.159990</td>
                <td>state_flag</td>
            </tr>
            <tr class="alternateRow">

                <td>72</td>
                <td>remove_items_states</td>
                <td>0.160000</td>
                <td>state_flag</td>
            </tr>
            <tr class="alternateRow">
                <td>test.cpp</td>
                <td>72</td>
                <td>remove_items_states</td>
                <td>0.160000</td>
                <td>state_flag</td>
            </tr>
        </tbody>

您可以使用 jQuery。例如：jsfiddle

// Change the selector if needed
var $table = $('table.scrollTable'),
    $bodyCells = $table.find('tbody tr:first').children(),
    colWidth;

// Adjust the width of thead cells when window resizes
$(window).resize(function() {
    // Get the tbody columns width array
    colWidth = $bodyCells.map(function() {
        return $(this).width();
    }).get();

    // Set the width of thead columns
    $table.find('thead tr').children().each(function(i, v) {
        $(v).width(colWidth[i]);
    });    
}).resize(); // Trigger resize handler
