I am wondering if there is any tool that can help me work with tables in LaTeX. Specifically I'd like to be able to import HTML tables (or small Excel tables) into LateX

Are there tools that can help me do that painlessly?

Bear in mind that properly formatted tables for publication are not the same as the sort of thing that Excel, etc., produce. So even if you can import stuff quickly you may well have to work on the appearance. – Joseph Wright Aug 16 '10 at 7:48

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!

I have started a comprehensive list -- do you want to add a description of Calc2LaTeX, especially comparing it to current Excel2LaTeX? – krlmlr Mar 29 '12 at 7:31
Have just installed calc2latex, via sudo apt-get install libreoffice-writer2latex apt says this if for writer and calc. I see it in the extension manager. However I can not workout how to use it: Where is it? What do I have to click? – richard May 29 at 14:07

Check out this page http://www.ctan.org/tex-archive/help/Catalogue/entries/datatool.html and tools it links ie csvtools and pgfplotstable. They allow you to keep the data in csv or tsv format and configure typesetting options in .tex source. I have used pgfplotstable and it is very handy.

This is a good alternative to directly importing the data, particularly for large data sets or ones that will change over time. – Joseph Wright Aug 16 '10 at 7:50
I agree: CSVtools is very powerful and it's worth considering the csv way against the conversion from excel to the latex code, especially for large amount of data. In case of small tables, converting from excel could be more convenient. – Alessandro Cuttin Aug 17 '10 at 10:06
But when the table is small inputing isn't much of a problem. – Leo Liu Aug 17 '10 at 10:27
csvtools has been replaced by the datatool package (by the same author.) – Alan Munn Mar 20 '11 at 0:28
@Leo: I have started a comprehensive list -- do you want to add datatool? I'm not familiar with it. – krlmlr Mar 29 '12 at 7:30

The on-line LaTeX table editor at http://truben.no/latex/table/ is very handy. You can import your data in LaTeX, JSON or CSV format (the last of these being relevant to this question), and export it in LaTeX format (among numerous other formats). It's also very easy to insert/delete columns, etc., and change the formatting.

If you use TeXShop on the Mac, there is a built-in macro for pasting copied spreadsheet cells directly into your latex sources into a variety of popular table formats. The same scripts are also available for other Mac text editors here: csv2latex. (OB Disclaimer: I am the author.)

you can try this one: http://www.tablesgenerator.com/latex_tables#

it can generate latex table codes as well as other formats like markdown, html, wiki etc.

Perhaps you will feel comfortable defining tables in CALS syntax immediately in LaTeX.

The CALS table model is the historic precursor of the HTML table model. It is easier in use and offers more capabilities than tabularx.

Here is the documentation of the cals package:

Calc2LaTeX is the best option as said above, but if you're constantly switching computers or on a mac (I regularly do both), then an online editor is a good option.

I have found http://www.tablesgenerator.com/latex_tables# is the best online editor, as efinal recommended, because it also converts & % to \& \% straightforwardly, which http://truben.no/latex/table/ doesn't, as far as I can tell. The Truben Table Editor was no good to me as the paste command simply pasted an entire table into one cell, fustratingly.
