How do you create a header cell in an HTML table?

To create a header cell within an HTML table, the correct approach is to use the tag. This tag is specifically designed for defining header cells, which are typically used to represent the headings of columns or rows in a table. Header cells are rendered in bold and centered by default, making it visually clear that they contain important label information relevant to the data in the corresponding cells.

Using the tag is incorrect because there is no such tag in HTML for defining rows. Rows are created using the tag, which stands for "table row." The tag also does not exist in HTML; standard table data is enclosed in the tag. Lastly, the

tag is not applicable here as it is intended for defining header sections in a document, not for individual cells within a table. Therefore, the tag is the only appropriate choice for creating header cells in an HTML table.
