I think that, if you are able to import your html tables in Excel or OpenOffice Calc, these tools are what you need:
The first one is a macro you add to your Excel, and provides you with an extra button to create the LaTeX code for the table from a set of selected cells, ready to be pasted in your .tex source.
The second, is an extension of OO, but should work in the same way.
Edit: there is also html2LaTeX, but I never used it.
Happy TeXing!
Often, I have the use-case that I want to convert a given data table into a "suitable" LaTeX table.
Typically, my data is of numeric type and requires number formatting, perhaps alignment at a decimal point, and in most cases, it requires elementary post-processing (like quotients, differences, gradients).
Since I needed such stuff very often, I wrote some C++ scripts which generated .tex files. It was useful - but I realized very early that it is insufficient; it is just not flexible enough and -as any external tool- produces unwanted complications due to the many tools involved.
My solution is the LaTeX package pgfplotstable. It is a LaTeX table generator, i.e. it converts input data explicitly by a set of configurable rules into something like \begin{tabular}....\end{tabular}.
DISCLAIMER NOTE: I wrote the package.
Among its features are
- separation of data + format
- data in form of external data files (CSV with customizable separators) or inline tables (inside of the
.tex file)
- central format definition (for example in the preamble or in form of styles)
- format numbers with the full power of LaTeX
- supports simple text columns as well
- simple support for alternating row colors (
colortbl)
- simple support for standart LaTeX table packages (
booktabs, longtable, colortbl, multirow, \multicolumn,...)
- can produce completely new columns containing postprocessed data, with the powerful
pgf math engine
- can convert single-column output to two-column output
- is written completely in TeX (no external tools required)
- highly customizable
- has a manual with lots of examples.

Excel supports merged cells, and you can convert a table to LaTeX using the Excel2LaTeX add-in (this works for multirow and multicolumn cells). However, you would have to manually change the generated code if you want to use the
tabularxenvironment.See also: Comprehensive list of tools that simplify the generation of LaTeX tables.
