To create table rows and columns in HTML, use the <table> tag. A table consist of rows and columns, which can be set using one or more <tr>, <th>, and <td> elements. A table row is defined by the <tr> tag. For table rows and columns, <tr> tag and <td> tag is used respectively. The <td> tag
Just keep in mind, a lot of table attributes such as align, bgcolor, border, cellpadding, cellspacing aren’t supported by HTML5. Do not use them. Use the style attribute to add CSS properties for adding a border to the table. We’re also using the <style> tag to style the table borders.

Example
You can try to run the following code to create table rows and columns in HTML.
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
}
</style>
</head>
<body>

<th>Header: This is row1 column2</th>
</tr>

<td>This is row2 column1</td>
<td>This is row2 column2</td>
</tr>
</table>
</body>
</html>Output
