Visual Editor format question

This is the format that I get with an automatic build of a report.

--------------------------

{BEGIN lastname_fieldheadercolumn}

<td>

{BEGIN lastname_fieldheader}

<b>Lastname</b>

{END lastname_fieldheader}

</td>

{END lastname_fieldheadercolumn}

-------------------------

My questions are:

1. Are all of these {tags} required? Can I leave any out when I build my custom form?
   
2. When I add multiple data elements into the same cell, do I need multiple header tags? and END tags?
   
3. Lastly, is there any "easier <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=10445&image=1&table=forumtopics' class='bbc_emoticon' alt=':blink:' /> " way to edit these html templates? Visual Editor doesn't work reliablily.
   
   Is there any trick to using Dreamweaver or Frontpage that will keep the 5 related {tags} together properly?
