: Define the main content of the table
<tfoot> tags in HTML tables are used to semantically divide table structures. 1. <thead> defines the table header, including the column title , which facilitates fixing the table header, printing control and style settings; 2.
<tbody> wraps data rows, improves readability and supports JavaScript operation data; 3.
<tfoot> is used to summarize information at the bottom, and even if the code is in front, it will be rendered by the browser at the bottom of the table, which helps load the footnote content first. 
<thead> , <code><tbody> and <code><tfoot> tags in the HTML table structure are used to semantically divide different parts of the table. They themselves do not directly affect the appearance of the table, but can improve code readability, enhance semantic expression, and optimize the display and accessibility of the table in some scenarios. <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175251450521251.jpeg" class="lazy" alt="What are <thead>, <tbody>, and <tfoot> used for?"> ,</tfoot>

<tfoot> used for?" /><h2> <code><thead> : defines the table header part of the table<p> This tag is used to wrap the part of the table that represents the "column title". Usually it contains one or more <code><tr> (table rows), and each <code><tr> contains several <code><th> (table header cells).<p> for example: </p>
<img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175251450625128.jpeg" class="lazy" alt="What are <thead>, <tbody>, and <tfoot> used for?"> ,</th>

<tr>
<th>Name</th>
<th>Age</th>
<th>City</th>
</tr>
</head></pre><p> The advantage of using <code><thead> is that the browser can identify which content is the header, which is convenient for fixing the header, printing control and other processing. It is also convenient to use CSS to set the header style separately, or use JavaScript to manipulate the header content.
<tbody> : Define the main content of the table
This part is the "data area" of the table, which contains most of the data rows that are actually displayed. It should be placed after <thead> (if any), and there can be multiple <tbody> , for example to group and display different categories of data.
,<tbody> , and<tfoot> used for?" /> Common writing methods are as follows:
<tbody>
<tr>
<td>Zhang San</td>
<td>28</td>
<td>Beijing</td>
</tr>
<tr>
<td>Li Si</td>
<td>34</td>
<td>Shanghai</td>
</tr>
</tbody> Using <tbody> can make the table structure clearer and facilitate batch manipulation of data rows through JavaScript, such as sorting, filtering, highlighting the current row, etc.
<tfoot> : define the bottom summary information of the table
If you want to display totals, averages, or other summary information at the bottom of the table, you can wrap these contents with <tfoot> . It usually follows <thead> and <tbody> .
Example:
<tfoot>
<tr>
<td>Total</td>
<td>62</td>
<td></td>
</tr>
</tfoot> Although the visual content of <tfoot> will appear at the bottom of the table, in HTML code, you can also put it at the beginning of the table, and the browser will still automatically render it at the bottom. This feature may be useful when you need to load the footnote content first.
In general, using these three tags reasonably can make the table structure clearer and have stronger semantics, and can also achieve more functions in conjunction with CSS and JavaScript.
Basically that's it.

Choosing the correct display value in CSS is crucial because it controls the behavior of elements in the layout. 1.inline: Make elements flow like text, without occupying a single line, and cannot directly set width and height, suitable for elements in text, such as; 2.block: Make elements exclusively occupy one line and occupy all width, can set width and height and inner and outer margins, suitable for structured elements, such as; 3.inline-block: has both block characteristics and inline layout, can set size but still display in the same line, suitable for horizontal layouts that require consistent spacing; 4.flex: Modern layout mode, suitable for containers, easy to achieve alignment and distribution through justify-content, align-items and other attributes, yes

How does provide and inject allow for deep component communication without prop drilling in Vue?
Jun 20, 2025 am 01:03 AM
In Vue, provide and inject are features for directly passing data across hierarchical components. The parent component provides data or methods through provide, and descendant components directly inject and use these data or methods through inject, without passing props layer by layer; 2. It is suitable for avoiding "propdrilling", such as passing global or shared data such as topics, user status, API services, etc.; 3. Note when using: non-responsive original values ??must be wrapped into responsive objects to achieve responsive updates, and should not be abused to avoid affecting maintainability.
