The border-collapse property in CSS is used to set whether the table borders are merged. It has three values, where separate represents a detached border, collapse represents a merged border, and inherit indicates inheritance of attributes from the parent.

When making a table, we can use the border-collapse attribute to merge the two borders into one, making the border more beautiful.

The border-collapse property sets whether the borders of the table are merged into a single border or are displayed separately as in standard HTML.

Examples are as follows:

Table {border-collapse:collapse;} table, td, th {border:1px solid black;} FirstnameLastnameBillGatesStevenJobs
