HTML tables are fundamental structures for displaying data in web pages. They consist of several key elements working together. The table element serves as the main container, while tr elements define individual rows. Within each row, we use th elements for headers and td elements for data cells.
Let's look at a practical HTML table example. We start with the table tag to create the container. Then we add our first row using tr, which contains header cells defined with th tags for Name, Age, and City. Next, we create data rows, each starting with tr and containing td elements for the actual data like John, twenty five, New York City.
When a browser encounters an HTML table, it follows a specific rendering process. First, it parses the HTML structure to understand the table elements. Then it creates a grid layout, calculating the optimal column widths based on content. Finally, it positions each cell within its designated row and column, applying any CSS styling and borders to create the final visual table.
HTML tables offer advanced features for better organization and functionality. The thead, tbody, and tfoot elements help structure tables semantically, grouping header, body, and footer content respectively. The caption element provides a title for the table. Additionally, colspan and rowspan attributes allow cells to span across multiple columns or rows, creating more complex table layouts for sophisticated data presentation.
To summarize what we have learned about HTML tables: They use specific elements like table, tr, th, and td to create structured data displays. Browsers render these as organized grids with calculated layouts. Advanced features like thead, tbody, and cell spanning provide additional functionality. Tables offer semantic meaning for tabular data and require proper tag nesting for correct display.
