Explanation:

The attribute that defines the number of columns in a group is the span attribute with the value of a number. This attribute specifies the number of columns that a cell should span within a group of columns.

Here is a detailed explanation of the span attribute:

- span Attribute:
- The span attribute is used in HTML tables to define the number of columns that a cell should span horizontally.
- It is specified as a number that represents the number of columns to span.
- This attribute helps in creating table layouts where certain cells need to cover multiple columns.

- Example:
- Suppose we have a table with 4 columns, and we want a cell in the first row to span across all 4 columns. We can use the span attribute to achieve this.
-




This cell spans across 4 columns



- Usage:
- The span attribute is commonly used in conjunction with the colspan attribute to create complex table structures.
- It helps in organizing and structuring tabular data in a visually appealing manner.

By using the span attribute with the appropriate value, we can control how many columns a cell should span within a group of columns in an HTML table.
