How to merge cells in an HTML table with colspan and rowspan

How to merge cells in an HTML table with colspan and rowspan

To merge cells in HTML tables, you need to use the colspan and rowspan attributes. 1. Use colspan to make cells span multiple columns, such as creating a title that spans three columns. At this time, other cells in the row need to be reduced accordingly to keep the number of columns consistent; 2. Use rowspan to make cells span multiple rows, such as overwriting three rows, and the cell will no longer be added repeatedly in subsequent rows; 3. You can use colspan and rowspan to achieve complex layouts at the same time, but you need to ensure that the total number of columns per row matches and does not repeatedly fill the spanned cells. The cross-domain value can be correctly calculated to ensure the table structure is aligned.
