The <tr> tag specifies a row in an HTML table. The cells inside it are defined using <th> (a header cell) or <td> (a standard cell) elements. Both the <td> and <th> tags support the colspan attribute for additional control over how cells span across or fit into columns. This attribute allows defining how many columns wide the cell must be (the default being 1). You can use the rowspan attribute on cells if you want to specify that they must span more than one row.

Some tables can also include the <col>, <colgroup>, <caption>, <tfoot>, <tbody>, and <thead> elements.

The <tr> element is declared inside the <table> tag.

All the rows in a table contain an equal number of cells, which is equivalent to the number of cells in the longest row. If there are fewer cells in a row, then the browser will automatically fill the row, placing empty cells at the end of it.

If you need to emphasize that there is no data in other cells, then create cells without content where necessary.

The cells added by browser have no borders, and if they go after each other, they will be shown as one integrated cell.

To customize the look of the table, use CSS properties.


The <tr> tag comes in pairs. The content is written between the opening (<tr>) and closing (</tr>) tags.


Example of the HTML <tr> tag:

<!DOCTYPE html>
    <title>Title of the document</title>
      table {
        width: 80%;
        margin: 30px auto;
        border-collapse: collapse;
      td {
        padding: 10px;
        border: 1px solid #666;
