Answer 1

只需改变这段代码就像其他代码一样。

这是要改变的代码

<td><button type='button' name='edit' id='edit' **value='".$res['user_id']."'** class='btn btn-warning btn-sm' style='width:72px;'/></td>
<td><button type='button' name='delete' id='delete' value='".$res['user_id']."'  class='btn btn-danger btn-sm' onclick='asd();' style='width:72px;'/></td>

像这样

<td><button type='button' name='edit' id='edit' class='btn btn-warning btn-sm' style='width:72px;' value='{$res['user_id']}'>{$res['user_id']}</button> </td>
<td><button type='button' name='delete' id='delete' value='{$res['user_id']}'  class='btn btn-danger btn-sm' onclick='asd();' style='width:72px;' value='{$res['user_id']}'>{$res['user_id']}</button></td>

Answer 2

您需要将文本放在<button></button>标记之间

<button type='button' name='edit' id='edit' **value='".$res['user_id']."'** class='btn btn-warning btn-sm' style='width:72px;'>EDIT</button>

<button type='button' name='delete' id='delete' value='".$res['user_id']."'  class='btn btn-danger btn-sm' onclick='asd();' style='width:72px;'>
    DELETE
</button>
