Question

在此示例中，当给出tbody属性为＆＃34;显示为块＆＃34;结果是预期的。但当给出＆＃34;显示为table-header-group＆＃34;我不能将表行（tr）宽度设置为相应的th。请帮帮我。

段：

＆＃13;

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

＆＃13;

table.scroll {
  width: 100%;
  /* Optional */
  /* border-collapse: collapse; */
  border-spacing: 0;
  border: 2px solid black;
}
table.scroll tbody {
  display: block;
}
table.scroll thead {
  display: table-header-group;
}
thead tr th {
  height: 30px;
  line-height: 30px;
  /*text-align: left;*/
}
table.scroll tbody {
  height: 100px;
  overflow-y: auto;
  overflow-x: hidden;
}
tbody {
  border-top: 2px solid black;
}
tbody td,
thead th {
  // width: 20%; /* Optional */  border-right: 1px solid black;
}
tbody td:last-child,
thead th:last-child {
  border-right: none;
}

Ajax数据表将是您的最佳解决方案。这是您可以实现的链接。 Data table example 和Scrolling example。在第二个链接中找到滚动示例

$(document).ready(function() {
    $('#example').DataTable( {
        scrollY:        '50vh',
        scrollCollapse: true,
         paging:         false
     } );
} );

如果需要，您还可以使用像素设置滚动功能。使用这个插件你不需要操纵表。它将重新排列表格。

table-header-group不支持滚动
