jQuery DataTable：在表头上搜索单个列
我已按照单个列搜索（文本输入）和单个列搜索（选择输入）上的步骤在jQuery DataTable上使用多个filter，并且页脚上有多个filter。 另一方面，我想将这些filter移动到DataTable的标题，但不能将它们水平对齐，如下图所示。 有一些例子是自定义过滤 – 范围搜索 ，但它们也没有对齐。 是否有可能做到这一点？
$(document).ready(function() { // Setup - add a text input to each footer cell $('#example tfoot th').each( function () { var title = $(this).text(); $(this).html( '' ); } ); // DataTable var table = $('#example').DataTable(); // Apply the search table.columns().every( function () { var that = this; $( 'input', this.footer() ).on( 'keyup change', function () { if ( that.search() !== this.value ) { that .search( this.value ) .draw(); } } ); } ); } ); 
这里solution您的问题请添加必要的数据表配置。
使用CSS将列filter从页脚移动到表头，即只使用

希望这对你有所帮助。
这可以通过CSS实现。
$(document).ready(function() { // Setup - add a text input to each footer cell $('#example tfoot th').each( function () { var title = $(this).text(); $(this).html( '' ); } ); // DataTable var table = $('#example').DataTable({ "paging": false, "info": false, "scrollY": 200, "scrollX": true }); // Apply the search table.columns().every( function () { var that = this; $( 'input', this.footer() ).on( 'keyup change', function () { if ( that.search() !== this.value ) { that .search( this.value ) .draw(); } } ); } ); } );

这里是数据表中单个列搜索的解决方案。 它还用于使用正则表达式进行多行值搜索：
$('#' + tableId + ' thead tr').clone(true).appendTo('#' + tableId + ' thead'); $('#' + tableId + ' thead tr:eq(1) th').each(function (i) { // Creating Clone Header for Filter TextBox var title = $(this).text(); if (excludeTitle.indexOf(title.trim()) == -1) { // check table column header to add filter textBox $(this).html(''); $('input', this).on('keyup change', function () { if (table.column(i).search() !== this.value) { var sp1 = this.value; var regex_check = null; try { regex_check = new RegExp(sp1);} catch (error) { alert('Search parameter is not in correct format.'); return false; } table.column(i).search(sp1, true).draw(); } }); } else { $(this).html(''); } });
