Border for table th not working in IE

Question

I have datagrid table with some styles applied to it. Everything is working fine Chrome and Firefox but border is not applied to table thead th in IE. the borders are seen when I apply the same styles to table tbody td. In the following styles, border-left is not working in IE.

.datagrid table thead th {
color: #4180ab;
font-size: 12px;
font-weight: bold;
line-height: 30px;
text-align: center;
border-left: 1px solid #a8cbd1;
background: #f1f6fa;
}

//HTML Markup

<table cellpadding="0" cellspacing="0" border="0" class="display" id="example">
<thead class="thead">
    <tr>
        <th>No</th>
        <th>Application Number</th>

Answer 1

The best solution I've seen to this problem is applying

background-clip: padding-box;

to the th elements.

IE seems to render the background over the borders in some situations without this.
