DataTables.js-表在页面加载时未加载初始100％全宽

Question

DataTables.js-表在页面加载时未加载初始100％全宽

我正在使用DataTables固定标头功能将PHP页面与表一起加载。在页面渲染时，我似乎无法使表格处于页面负载的100％。它开始于压缩（加载时），然后扩展（一次页面渲染）。

我试图通过在PHP中进行输出缓冲来解决此问题，但无法获得压缩效果，然后扩展消失。

初始化代码（在脚本底部）

$(document).ready(function() {
    $('#summary_table').DataTable( {
        "scrollY": 400,
        "scrollX": true,
         "bSort": false,
         "bPaginate": false,
         "autoWidth": false 
    } );

    $(".dataTables_wrapper").css("width","100%");
});

（表在加载过程中被压缩，但随后达到100％。）

我该如何解决这个问题？

Answer 1

对于Bootstrap 4用户

如果在表中使用Bootstrap类，则可能会遇到此宽度问题。要解决此问题，请使用datatable默认选项"autoWidth": false

启用或禁用自动列宽计算。如果使用来传递表格宽度，则可以将其禁用为优化（需要花费有限的时间来计算宽度）

$('#example').dataTable( {
    "autoWidth": false
});

Answer 2

我相信我已经解决了这个问题。我使用的是较旧的版本。

升级到 10.1 并遵循下面的表格宽度说明后，我解决了我的问题。

我将 (width="100%") 添加到我的表格标记中，现在它保持在 100%

所以而不是

<table id="summary_table" class="display nowrap" style="width: 1000" border=1>

Run Code Online (Sandbox Code Playgroud)

width: 1000我将仅将绝对宽度设置为 1000 像素（我忘记添加单位后缀）的样式替换px为 100% `width='100%' 的百分比值，并且解析表标记将读取。

<table id="summary_table" class="display nowrap" width="100%" border=1>
