td_PHP tutorial on incomplete supplement of circular tables in smarty templates

It is a bad thing to use tables to read data in a loop in smarty templates. Where should you add tags and where should you add tags? It’s easy to say. If you encounter The kind that requires adding the colspan tag is really troublesome. However, I have already found a way to solve this problem. I will record it below in case I encounter this situation again. The specific code is as shown below and needs to be modified according to the actual situation:

{section loop=$student_list name=list}
{if $smarty.section.list.first || $smarty.section.list.rownum%5==1}<tr>{/if}
<td>{$student_list[list].name}</td>
{if $smarty.section.list.last == 1 && $smarty.section.list.rownum%5 != 0}
<td colspan="{math equation=x-y x=5 y=$smarty.section.list.rownum%5}"> </td>
{/if}
{if $smarty.section.list.last || $smarty.section.list.rownum%5==0}</tr>{/if}
{/section}

Note: The above example loops through a five-column table
