TableTools is a Firefox extension that lets you sort, filter and export tables from any web page. After installing the extension and restarting Firefox, find a web page that includes tables (this search might help) and right-click on a table to find a lot of interesting features:

* sort a column, depending on the type of elements (text, numbers, dates)
* filter the rows of a table by selecting elements from a drop-down or by entering your search terms, like in the screenshot below. You can even enter regular expression to filter more complex patterns. After typing the query, press Enter or click outside the active input box.
* export the entire table as tab-delimited text, HTML code or just the filtered rows


This might be helpful if you want to insert some partial data from a table in a document, a site or in Google Spreadsheets, which only supports filtering using a limited gadget. For Google Spreadsheets, choose the option to copy the rows as tab-delimited text.
