is there any other solution to make those rows empty

Answer 1

The <td> tag is for cells that contain data

Answer 2

<td> tags are used to give table data in a HTML table. Like if you've 4 data in a row then you'd be using 4 <td> tags inside a <tr> tag and so if you've multiple rows you'd be using multiple<tr> tags inside a <table>.
