Limited support is offered.
The <TT>tabbing</TT> environment translate to a flexible <TT>tabular</TT>-like
environment.
Inside this environment, the command <CODE>\kill</CODE> ends a row, while
commands
<CODE>\=</CODE> and <CODE>\></CODE> start a new column.
All other tabbing commands do not even exist.<BR>

These environments are supported, using HTML
<CODE>TABLE</CODE> element, rendering is satisfactory in most (not too
complicated) cases.
By contrast with L<sup>A</sup>T<sub>E</sub>X,
some of the array items always are typeset in display mode.
Whether an array item is typeset in display mode or not depends upon
its column specification,
the <CODE>l</CODE>, <CODE>c</CODE> and <CODE>r</CODE> specifications open display mode
while the remaining <CODE>p</CODE> and <CODE>@</CODE> do not.
The <CODE>l</CODE>, <CODE>c</CODE>,<CODE>r</CODE> and <CODE>@</CODE> specifications
disable word wrap, while the <CODE>p</CODE> specification enables it.<BR>
<BR>
Entries in a column whose specification is <CODE>l</CODE> (resp. <CODE>c</CODE> or
<CODE>r</CODE>) get left-aligned (resp. centered or right-aligned)
in the horizontal direction.
They will get top-aligned in the vertical direction if there are
other column specifications in the
same array that specify vertical alignement constraints
(such as ``<CODE>p{</CODE><I>wd</I><CODE>}</CODE>'', see below).
Otherwise, vertical alignement is unspecified.<BR>
<BR>
Entries in a column whose specification is <CODE>p{</CODE><I>wd</I><CODE>}</CODE>
get left-aligned in the horizontal direction and
top-aligned in the vertical direction
and a paragraph break reduces to one line break inside them.
This is the only occasion where
H<FONT SIZE=2><sup>E</sup></FONT>V<FONT SIZE=2><sup>E</sup></FONT>A makes a distinction between LR-mode and paragraph mode.
Also observe that the length argument <I>wd</I> to the <CODE>p</CODE>
specification is ignored.<BR>
<BR>
Some L<sup>A</sup>T<sub>E</sub>X array features are not supported at all:
<UL><LI>
Optional arguments to <CODE>\begin{array}</CODE> and
<CODE>\begin{tabular}</CODE> are ignored.
<LI>The command <CODE>\vline</CODE> does not exists.
</UL>
Some others are partly rendered:
<UL><LI>
Spacing between columns is different.
<LI><CODE>@</CODE> formatting specifications in <CODE>\multicolumn</CODE>
argument are ignored.
<LI>If a <CODE>|</CODE> appears somewhere in the column formatting
specification, then the array is shown with borders.
<LI>The command <CODE>\hline</CODE> does nothing if the array has borders
(see above). Otherwise, an horizontal rule is outputed.
<LI>The command <CODE>\cline</CODE> ignores its argument and is equivalent
to <CODE>\hline</CODE>.
<LI>Similarly the command
<CODE>\extracolsep</CODE> issues a warning and ignores its argument.
</UL>
Additionally, the <CODE>tabular*</CODE> environment is
recognized and gets renderered as an HTML table with an advisory
width attribute.<BR>
<BR>
By default, H<FONT SIZE=2><sup>E</sup></FONT>V<FONT SIZE=2><sup>E</sup></FONT>A implements the <TT>array</TT> package
(see [<CITE><A HREF="manual050.html#latexbis">L<sup>A</sup>T<sub>E</sub>X-bis</A>, Section 5.3</CITE>] and section <A HREF="manual034.html#arraypack">B.17.2</A> in this
document), which significantly extends the
<CODE>array</CODE> and <CODE>tabular</CODE> environments.<BR>
