Tables can be embedded in emails easily. If a Thunderbird user receives an email that contains a table he is up for a problem though. It does not matter how he tries to copy the table or selected parts of it because the end result will always be that the formatting is lost. There is no way to copy a table from Thunderbird into Microsoft Excel or similar applications and retain the rows and columns of that table.
Table 2 Clipboard is a Thunderbird extension that adds this much needed feature to Thunderbird. The extension can be used to copy a table or part of it to the clipboard retaining the format of it. Pasting that data into a spreadsheet will put the data into rows and columns just like the original data was.
The add-on has to be downloaded from Mozilla and installed using the Tools > Addons menu in Thunderbird. A click on Install in that menu will open a file browser where the downloaded extension has to be selected.
