        <p>; tag支持不同的屬性,我們一一看看:</p>
        <p><strong>align:</strong> 此屬性有助于參考其內(nèi)容對齊文本。</p>
        <p><strong>valign:</strong>這些屬性有助于將內(nèi)容對齊到其文本的垂直對齊方式。</p>
        <p><strong>char:</strong>關(guān)于</p>
        </tr>
        <tfoot>的重要屬性之一標(biāo)簽用于將標(biāo)題單元格中的文本與其相關(guān)字符對齊。
        <p><strong>Charoff</strong>:這是用于設(shè)置 char 屬性的一個更重要的屬性。這些類型的屬性以數(shù)字形式定義。</p>

        <tfoot>的位置通過定義諸如向左對齊、向單元格中心對齊、向單元格右側(cè)對齊之類的值來標(biāo)記標(biāo)簽,在文本內(nèi)容周圍插入或調(diào)整特定的 space0020,用于將文本內(nèi)容與具有最小偏移量的特殊字符對齊的字符等。
        <p>此標(biāo)簽可以與不同的 CSS 屬性一起使用,如下所示:</p>
        <p><strong>text-align:</strong>此屬性有助于在文本內(nèi)容的幫助下直接左對齊、右對齊、對齊或居中對齊頁腳文本。</p>
        <p><strong>bgcolor:</strong>為了使表格單元格更具吸引力,此屬性幫助我們將顏色設(shè)置為列單元格的背景。</p>

        <p>;元素與 <thead> 組合使用。和它將定義表格的每個元素,如頁眉、頁腳和正文。該標(biāo)簽將使用一個或多個<tr> </tr>
        </thead></p>
        <tfoot> 內(nèi)的元素元素,因此它將有助于顯示表格內(nèi)容的摘要。它應(yīng)該放在桌子的底部。 <tfoot>的主要工作是tag是為了維護(hù)大表數(shù)據(jù)。這將允許用戶獨立顯示表格的內(nèi)容,從而讓用戶感受到更好的可用性體驗。
        <p>讓我們看一個例子來了解 </p>
        <tfoot> 到底是如何實現(xiàn)的。標(biāo)簽將在 HTML 中工作:
        <p><strong>示例:</strong></p>
        <pre class="brush:php;toolbar:false"><table>
        <thead>
        <tr>
        <th>Emp_ID<th>

        </thead>
        <tbody>
        <tr>
        <td>111</td>
        <td>John</td>
        <td>Developer</td>
        </tr>
        <tr>
        <td>112</td>
        <td>Krishna</td>
        <td>Tester</td>

        <td> 3 </td>
        </tr>
        </tfoot>
        </table></pre>
        <p>所以在上面的例子中,</p>

        <p>From all the above information, we can say that <tfoot> is one of the important tags in the table, which helps to display the table summary at the bottom of the table. It’s always necessary to put <tfoot> tag at <tbody> ends, so it will help the browser to render the table footer correctly.</p>
