Question

How do I get my datatable to get the following format:

             England   Germany   Holland   Spain   Germany   Russia   Japan

England         x

Germany                    x

Holland                             x

Spain                                         x

Germany                                               x

Russia                                                          x

Japan                                                                    x

I did get some answers before, but that was with another way. I actually want my datatable to be used in this. Also it would be nice if you could help me out on how to display the input on the correct coordinates.

best regards

My table
