我只是想知道你是否可以调整modal的宽度来适应它的内容，而不必将width属性设置为一个固定值。我也不想放置一个水平滚动条。我尝试过设置overflow-x属性，但没有成功。如果可能的话，我不想使用任何jQuery来实现这一点;只需更改CSS。screenshot如下所示：
下面是代码：

<!-- Modal -->
<div class="modal fade" id="tableWorklog" tabindex="-1" role="dialog">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header"> <!--Modal Header -->
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title">Member name's Worklog</h4>
      </div> <!-- /header -->
<div class="modal-body"> <!--Modal Body -->
    <table class="table table-striped">
        <thead>
            <tr>
                <th>Task Name</th>
                <th>Location</th>
                <th>Collab</th>
                <th>Description</th>
                <th>Start</th>
                <th>End</th>
                <th>Total</th>
                <th>Type</th>
                <th>Status</th>
                <th>Breaklog</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>task 1</td>
                <td>url</td>
                <td>NONE</td>
                <td>something about the task</td>
                <td>Date + time</td>
                <td>Date + time</td>
                <td><span class="label label-success">00:00:00</span></td>
                <td>Timer</td>
                <td><span class="label label-warning">ongoing</span></td>

            </tr>
        </tbody>
        <tfoot>
            <tr>

                <th>&nbsp;</th>
                <th>&nbsp;</th>
                <th>00:00:00</th>
                <th>&nbsp;</th>
                <th>&nbsp;</th>
