Another useful table tag is <TH> which is used for adding heading to columns. It replaces the <TD> tags of the first row. The <TH> tag helps in a logical table structure assisting in overall page design. Contents of <TH> are typically rendered in bold by browsers.

|Heading 1||Heading 2||Heading 3|
|Column 1||Column 2||Column 3|
