ie下table无法设置宽度的坑，解决方案：在td里面添加div把td宽度撑开即可。

<td><div style="width:180px">
                            <a data-b="2" class="btn btn-sm btn-info btnstart " title="Start">
                            <i class="ace-icon fa fa-play"></i></a>
                            <a data-b="4" class="btn btn-sm btn-success btnresume" title="Resume">
                                <i class="ace-icon fa fa-step-forward"></i></a>
                            <a data-b="c" class="btn btn-sm btn-info btnrefresh" title="Refresh">
                                <i class="ace-icon fa fa-refresh"></i></a>
                            <a data-b="9" class="btn btn-sm btn-danger btnremove" title="Remove">
                                <i class="ace-icon fa fa-remove"></i></a>
                            <a data-b="8" class="btn btn-sm btn-info btnarchived" title="Archived">
                                <i class="ace-icon fa fa-folder-open"></i></a>
                            </div>
                        </td>
<td><div style="width:180px">
