Strange phenomenon of Form nested Form in table_html/css_WEB-ITnose

Dear experts, I found that if there is a Form in the Table in the Form, the first nested form will always mess up the layout of the table, but the subsequent forms will not be affected.
For this reason, I found a workaround myself, and added a

below the external Form, so that there would be no problems with the subsequent nested forms, but I don’t know the reason. , please give me some guidance, thank you!

If you have multiple queries, please learn about AJAX.
