To center align text in table cells, use the CSS property text-align. The <table> tag align attribute was used before, but HTML5 deprecated the attribute. Do not use it. So, use CSS to align text in table cells. The text-align will be used for the <td> tag.
We’re using the style attribute for adding CSS. The style attribute specifies an inline style for an element. The attribute is used with the HTML <td> tag, with the CSS property text-align. HTML5 do not support the align tag,
Just keep in mind, the usage of style attribute overrides any style set globally. It will override any style set in the HTML <style> tag or external style sheet.
For text-align, set the table cell as left, right or center align

Example
You can try to run the following code to center align text in table cells in HTML
<!DOCTYPE html>
<html>
<head>
<style>
table, td, th {
border: 1px solid black;
width: 300px;
}
</style>
</head>
<body>
<h1>Our Technologies</h1>
<table>
<tr>
<th>IDE</th>
<th>Database</th>
</tr>
<tr>
<td style="text-align:center">NetBeans</td>
<td style="text-align:center">MySQL</td>
</tr>
</table>
</body>
</html>Output
