我正在使用 DataTables 固定标头功能加载带有表格的 PHP 页面。我似乎无法在页面呈现时让表格达到 100% 的页面加载。它以压缩（加载时）开始，然后展开（一旦页面呈现）。
我试图通过 php 中的输出缓冲来解决这个问题，但无法获得压缩然后扩展消失的效果。
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%");
});
编辑：
（表在加载期间被压缩，但随后变为 100%。）

我该如何解决这个问题？

我相信我已经解决了这个问题。我使用的是旧版本。
升级到 10.1 并按照下面的表格宽度说明操作后，我解决了我的问题。
我将 (width=“100%”) 添加到我的表格标签中，它现在保持在 100%
所以而不是
我替换了样式
width: 1000只是将绝对宽度设置为 1000 像素（我忘了添加px单位后缀），百分比值为 100% `width=‘100% ’ 和解析表标签将读取。我用这个问题的答案来形成我的回答
