javascript - Datatable、使用固定列时表格重叠

Question

根据我下面使用的代码，使用固定列时我的表格变得困惑。看来我的表格在左前 3 列重叠。我怀疑是scrollX 造成了这个问题，因为没有它，表格看起来完全没有问题。

有什么想法为什么会发生这种情况以及如何解决吗？

$('#example').DataTable( {
    scrollY:        "300px",
    scrollX:        true,
    scrollCollapse: true,
    paging:         false,
    fixedColumns:   {
        leftColumns:3
    }
} );

<table id="example" class="table table-striped table-bordered table-hover table-checkable" style="width:100%">
	    <thead>
	        <tr>
	            <th>First name</th>
	            <th>Last name</th>
	            <th>Position</th>
	            <th>Office</th>
	            <th>Age</th>
	            <th>Start date</th>
	            <th>Salary</th>
	            <th>Extn.</th>
	            <th>E-mail</th>
	        </tr>
	    </thead>
	    <tbody>
	        <tr>
	            <td>Tiger</td>
	            <td>Nixon</td>
	            <td>System Architect</td>
	            <td>Edinburgh</td>
	            <td>61</td>
	            <td>2011/04/25</td>
	            <td>$320,800</td>
	            <td>5421</td>
	            <td>t.nixon@datatables.net</td>
	        </tr>
	        <tr>
	            <td>Garrett</td>
	            <td>Winters</td>
	            <td>Accountant</td>
	            <td>Tokyo</td>
	            <td>63</td>
	            <td>2011/07/25</td>
	            <td>$170,750</td>
	            <td>8422</td>
	            <td>g.winters@datatables.net</td>
	        </tr>
	        <tr>
	            <td>Ashton</td>
	            <td>Cox</td>
	            <td>Junior Technical Author</td>
	            <td>San Francisco</td>
	            <td>66</td>
	            <td>2009/01/12</td>
	            <td>$86,000</td>
	            <td>1562</td>
	            <td>a.cox@datatables.net</td>
	        </tr>

	        </tr>
	    </tbody>

Answer 1

您应该正确阅读 dataTable 文档，并在代码中包含所有 css 和 js 外部脚本

您的问题是缺少一些外部脚本 Here is the working solution

$(document).ready(function() {
    var table = $('#example').DataTable( {
        scrollY:        "300px",
        scrollX:        true,
        scrollCollapse: true,
        paging:         false,
        fixedColumns:   {
            leftColumns: 2
        }
    } );
} );

/* Ensure that the demo table scrolls */
    th, td { white-space: nowrap; }
    div.dataTables_wrapper {
        width: 800px;
        margin: 0 auto;
    }
