TableTools

TableTools is a noteworthy software that offers a suite of advanced features for sorting, filtering, and copying HTML tables. With its two filtering modes, select filtering, and search filtering, you can filter your table data efficiently. Select filtering allows you to filter data by selecting values from each column's drop-down menu. On the other hand, search filtering offers greater flexibility by allowing you to search for a specific value in a column using keyword(s) or JavaScript regular expressions.

One of the most significant advantages of using TableTools is its smart sorting/select filtering. It can effectively detect various data types, including date/time stamps, numbers (including scientific notations), major currencies, IP addresses, or plain text. The context menu provides users with the freedom to force-sort column data as any of the predefined data types. For a detailed feature list, please visit the demo page provided.

If you're looking for a reliable tool to manage your data tables, TableTools is the perfect tool. It offers better sorting and filtering capabilities than MS Excel and can work directly in Firefox. One of the best aspects of TableTools is that you can copy the entire table into Excel, making it easy to use the data for graphing or further analysis.

However, there are limitations to TableTools when it comes to more complex situations such as nested tables, colspan, and rowspan. Though these features may not work as effectively as one would like, it is due to the lack of standardization and complexity in these scenarios. Nonetheless, TableTools remains an exceptional tool for anyone seeking to manage and analyze HTML tables efficiently.
