通過將<div>元素的display屬性設置為"table"，我們可以將其作為一個表格元素來使用。下面是一個簡單的代碼示例，演示了如何創建一個居中顯示的表格：
<div style="display: table; margin: 0 auto;"> <!-- 在這里添加<table>元素的內容 --> </div>
上述代碼中，我們通過將<div>元素的display屬性設置為"table"，將其視為一個表格元素，并使用margin屬性將其水平居中顯示。通過調整margin屬性的值，我們可以實現居中顯示的效果。
除了通過設置display和margin屬性來實現居中顯示外，我們還可以使用另一種方法，即通過設置<div>元素的position屬性為"relative"，然后再將內部的<table>元素的position屬性設置為"absolute"，并將left和top屬性值都設置為"50%"，再結合使用transform屬性中的"translate"函數，將表格元素向左和向上平移自身寬度和高度的一半。
<div style="position: relative; width: 100%; height: 100vh;"> <table style="position: absolute; left: 50%; top: 50%; transform: translate(-50%, -50%);"> <!-- 在這里添加<table>元素的內容 --> </table> </div>
上述代碼中，我們通過設置<div>元素的position屬性為"relative"，將其視為一個相對定位的元素，并在內部的<table>元素中設置position屬性為"absolute"，將其視為一個絕對定位的元素。然后，通過將left和top屬性值都設置為"50%"，以及使用transform屬性中的"translate"函數，將表格元素向左和向上平移自身寬度和高度的一半，實現了居中顯示的效果。
通過上述兩種方法，我們可以實現將一個表格居中顯示在頁面上的效果。在實際應用中，我們可以根據特定的需求選擇使用其中一種方法，或者根據具體情況進行組合使用，以達到預期的居中顯示效果。

-><div>The tag is one of the most commonly used block elements in HTML. It can be used to create a container for wrapping other HTML elements or for dividing the page layout. On the basis of the<div> element, the <table> element is also one of the commonly used elements in HTML, used to render tables. In some cases, we need to center a <table> element on the page. This article will describe in detail how to use the <div> and <table> elements to achieve centering, and provide some code examples to demonstrate the implementation methods.By setting the display property of the <div> element to "table", we can use it as a table element. Here is a simple code example that demonstrates how to create a centered table:
<div style="display: table; margin: 0 auto;"> <!-- Add content of <table> element here --> </div>
In the above code, we set the display property of the <div> element to "table" to treat it as a table element, and use the margin property to center it horizontally. By adjusting the value of the margin property, we can achieve the centering effect.
In addition to achieving centering by setting the display and margin properties, we can use another method. By setting the position property of the <div> element to "relative" and setting the position property of the internal <table> element to "absolute", we can set the left and top property values to "50%", and use the "translate" function in the transform property to translate the table element to the left and up by half its width and height.
<div style="position: relative; width: 100%; height: 100vh;"> <table style="position: absolute; left: 50%; top: 50%; transform: translate(-50%, -50%);"> <!-- Add content of <table> element here --> </table> </div>
In the above code, we set the position property of the <div> element to "relative" to make it a relatively positioned element, and set the position property of the internal <table> element to "absolute" to make it an absolutely positioned element. Then, by setting the left and top property values to "50%" and using the "translate" function in the transform property, the table element is translated to the left and up by half its width and height, achieving the centering effect.
With the above two methods, we can achieve the centering of a table on the page. In practical applications, we can choose one of the methods based on specific requirements, or combine them according to specific situations to achieve the desired centering effect.
