I've been working with Canvas apps for a year and a half and I've not, until this day, ever found a use for the Data Table control.
Now I have. I have a data source with so many columns with such variability in the length of the values, and decreasing relevance as you go right, that the ability for the user to scroll horizontally and adjust the width of the columns like in Excel is very welcome.
It does seem quite inflexible though. I'd like to have some column headers with a different fill colour. It's not much to ask really, but I can't seem to figure out how I can construct a formula in the HeadingFill property to pick up any value from HeadingDisplayName with which to build a Switch() or If(). I guess it's not possible, but if I've missed something I'd love to know how.
