Data is often transmitted as “tables,” for example, in CSV or HTML files <table>, but although they may look the same, they may have different implicit structures. For instance:
Height(cm) Weight (kg)
Pat 180 70
Sue 160 40
Jo 164 50
can be interpreted as an unordered list of objects (Person, indicating the height and weight of the attributes), in rectangular tables with uniform column data.
On the contrary, this is not a rectangular table, although it looks like one.
Dist(m)/Time(m) Hull Leeds London
Hull 0.0 69 229
Leeds 59 0.0 218
London 186 201 0.0
In fact, this is the typographic composition of two connected triangular matrices (distance and travel time) between cities in the UK.
