HTML Table Borders HTML tables can have borders of different styles and shapes. How To Add a Border To add a border, use the CSS border property on table, th, and td elements: Example: table, th, td {
border: 1px solid black;
}
Collapsed Table Borders To avoid having double borders like in the example above, set the CSS border-collapse property to collapse. This will make the borders collapse into a single border: Example: table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
Style Table Borders If you set a background color of each cell, and give the border a white color (the same as the document background), you get the impression of an invisible border: Example: table, th, td {
border: 1px solid white;
border-collapse: collapse;
}
th, td {
background-color: #96D4D4;
}
Round Table Borders With the border-radius property, the borders get rounded corners: Example: table, th, td {
border: 1px solid black;
border-radius: 10px;
}
Skip the border around the table by leaving out table from the css selector: Example: th, td {
border: 1px solid black;
border-radius: 10px;
}
Dotted Table Borders With the border-style property, you can set the appearance of the border. The following values are allowed: th, td {
border-style: dotted;
}
** Border Color** With the border-color property, you can set the color of the border. Example: th, td {
border-color: #96D4D4;
}
