Answer 1

You can generate an HTML script and add it in mail. Like if you want a tabular format, you can create the HTML script and attach it in mail.

Take the following for refference

DECLARE
   p_message_body   CLOB                := EMPTY_CLOB ();
   p_smtp_host      VARCHAR2 (20)       := ;
   p_smtp_port      VARCHAR2 (10)       := '25';
   p_message_type   VARCHAR2 (100)      := ' text/html';
   crlf             VARCHAR2 (2)        := UTL_TCP.crlf;
   ls_dt_start      VARCHAR2 (50);
   ls_dt_end        VARCHAR2 (50);
   l_mail_conn      UTL_SMTP.connection;
   pf_to_name       VARCHAR2 (100);
BEGIN
   BEGIN
      SELECT TO_CHAR (SYSDATE - 1, 'HH12:MI:SS AM'),
             TO_CHAR (SYSDATE + 1, 'HH12:MI:SS AM')
        INTO ls_dt_start,
             ls_dt_end
        FROM DUAL;
   EXCEPTION
      WHEN OTHERS
      THEN
         NULL;
   END;

   p_message_body :=
      '    ';
   p_message_body :=
         p_message_body

You can substitute the data you want with your table.
