I'm probably missing something, but it seems to me that a number of the nested
tables are redundant?
Couldn't a table cell <td></td> be thought of as a box? Boxed planes could be
separated rows without borders - that would maintain vertical alignment of
columns.
Below is an alternative HTML representation of the last example that uses 2
rather than 16 tables:
thh x=: 2 2 3 $ (i.&.>i.6),<<2 5$'abcdefghij'
<style type="text/css">
table.arraydisp td {font-family:monospace; border:solid black
1px;vertical-align: top;}
table.arraydisp tr.blank td {border:none;}
</style>
<table class="arraydisp" cellspacing="0" cellpadding="3"><tbody>
<tr>
<td> <br><br><br></td>
<td>0<br><br><br></td>
<td>0 1<br><br><br></td></tr>
<tr>
<td>0 1 2</td>
<td>0 1 2 3</td>
<td>0 1 2 3 4</td></tr>
<tr class="blank">
<td> </td>
<td> </td>
<td> </td></tr>
<tr>
<td>
<table class="arraydisp" cellspacing="0" cellpadding="3"><tbody>
<tr>
<td>abcde<br>fghij</td></tr></tbody>
</table></td>
<td> <br><br><br></td>
<td>0<br><br><br></td></tr>
<tr>
<td>0 1</td>
<td>0 1 2</td>
<td>0 1 2 3</td></tr></tbody>
</table>
