Tabletrick is an excel-addin built by BigBabou, based on an excel implementation by ukelele. The tool was tested in the federation Weetjewat and was built with the help of Weetjewat. Tabletrick converts the selected cells in your excel-worksheet to a conference-code that can be pasted into your post on the Hattrick conferences. It is used to create nicely aligned tables with every kind of data you like.
It can be found here.
Here are some examples of what Tabletrick can do.
