使用HTML / CSS在移动设备上激活表格

Question

我有这个表是更大的电子邮件的一部分。当用户的设备是手机或小屏幕时，我希望表格从2列/ 2行，到1列4行。想尽可能少地使用代码。

<table style="width:100%;table-layout:fixed;border-collapse:separate !important;border-spacing:20px 40px; font-family:Helvetica, Arial, sans-serif; color:#333333; font-size:16px; line-height:24px; font-weight:100;" class="bodywrapcenter">
  <tr>
    <td>
      Dr. Andrew Borg<br>
      Chapter Advisor<br>
      [email protected]<br>
    </td>
    <td>
      Stuart J. Sigman, PhD<br>
      Dean, College of Arts and Sciences<br>
    </td>
  </tr>
  <tr>
    <td>
      Dr. Dale Mancini<br>
      Chapter Advisor<br>
      [email protected]<br>
    </td>
    <td>
      David DeHaven, PhD<br>
      Dean, Graduate School of Business and Management<br>
    </td>
  </tr>
</table>

Answer 1

尝试使用bootstrap来响应表。

.table-responsive类创建响应表。然后，该表将在小型设备上水平滚动（低于768像素）。在大于768像素宽的任何物体上观看时。

根据需要使用.table-responsive {-sm | -md | -lg | -xl}来创建响应表到特定断点。从该断点开始，表将正常运行而不是水平滚动。

Answer 2

在你的css代码中给css移动断点下面的css，你已经完成了......

table.bodywrapcenter>tr>td {
    width: 100%;
    float: left;
}

Answer 3

/*
	Max width before this PARTICULAR table gets nasty. This query will take effect for any screen smaller than 760px and also iPads specifically.
	*/
	@media
	  only screen 
    and (max-width: 760px), (min-device-width: 768px) 
    and (max-device-width: 1024px)  {

		/* Force table to not be like tables anymore */
		table, thead, tbody, th, td, tr {
			display: block;
		}

		/* Hide table headers (but not display: none;, for accessibility) */
		thead tr {
			position: absolute;
			top: -9999px;
			left: -9999px;
		}

    tr {
      margin: 0 0 1rem 0;
    }
      
    tr:nth-child(odd) {
      background: #ccc;
    }
    
		td {
			/* Behave  like a "row" */
			border: none;
			border-bottom: 1px solid #eee;
			position: relative;
			padding-left: 50%;
		}

		td:before {
			/* Now like a table header */
			position: absolute;
			/* Top/left values mimic padding */
			top: 0;
			left: 6px;
			width: 45%;
			padding-right: 10px;
			white-space: nowrap;
		}

		/*
		Label the data
    You could also use a data-* attribute and content for this. That way "bloats" the HTML, this way means you need to keep HTML and CSS in sync. Lea Verou has a clever way to handle with text-shadow.

		td:nth-of-type(1):before { content: "First Name"; }
		td:nth-of-type(2):before { content: "Last Name"; }
		td:nth-of-type(3):before { content: "Job Title"; }
		td:nth-of-type(4):before { content: "Favorite Color"; }
