The Rowspan feature enables numerous cells of conjoining rows to be merged into a single row.
Let’s dive into this simple guide to learn how to use this feature in your table.
- First, go to the Table where you want to apply this feature. Then go to the Custom CSS/JS option of the table.

- Copy and paste the code from this file into the Custom Javascript option.
- Don’t forget to click on the Save Custom Javascript button.

- Now, go to the table column where you want to combine two rows.
- Click on the edit icon of that specific column.

- A pop-up will appear after clicking on the edit icon.
- Go to the Advanced Settings of the popup and Enter extra CSS classes into the column.
- You must enter the class name combine in the Extra Classes field to use the provided custom javascript in this case.

- After the custom javascript code is saved, it will be executed to combine the adjacent rows with identical data in the cells.
