<tr>: The Table Row element - HTML: Hypertext Markup Language
a mix of <td> (data cell) and <th> (header cell) elements. the source for this interactive example is stored in a github repository. if you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request. to provide additional control over how cells fit into (or span across) columns, both <th> and <td> support the colspan attribute, which lets you specify how many columns wide the cell should be, with the default being 1. similarly, you can use the rowspan attribute on cells to indicate they should span more than one table row. this can take a little practice to get right when building your tables. we have some examples below, but for more examples and an in-depth tutorial, see the html tables series in our learn...
