The model for handling tables in LaTeX and HTML are quite different.
They cannot be made to match easily, without the user adding extra markup into
the source document. Besides, what looks good in a table in print, does not
necessarily translate easily to how it is best represented onscreen.
For example, the \hline command occurs after a group of cells in the LaTeX
source; it causes a line to be drawn under the whole group of cells.
But in HTML each cell, or row of cells, has its decoration controlled by CSS
style properties.
CSS is not HTML, but is a whole separate architecture which allows for many,
many possibilities.
To add styles to a cell requires specifying a class name, then adding
properties to be used by that class. Shigeharu showed you how to do that.
At the time when LaTeX2HTML was under active development, browsers had limited
support for CSS, and different browsers would support a different set of
features, or would handle the same features differently. Thus there was little
incentive to code up actions for detailed styling in tables, since you could
not know what web surfers would actually see onscreen.
Without CSS, you can only ask for borders in all cells or no borders at all.
LaTeX2HTML simply takes the presence of an \hline anywhere to trigger showing
borders.
Besides, is the \hline meant to be affecting the styles of the cells above, or
below?
You could write some coding that does what you want, but would fail for someone
else.

Not just between, but all around.

Yes. But also because there is no canonical way to say what styles should be
applied to which cells, and how these should be combined with any other styling
requests.

Sure, but it is not well defined just what should happen in HTML and CSS.
Some user help is the best way to handle this.

This can be a very powerful mechanism, especially when the author can do a bit
of Perl programming.

Hope this helps,
