While the primary goal of wrapping material-components-web remains the same, they simply don't currently (or aren't planning on) supporting the entire spec. Happy to announce the first RMWC only component: DataTable. This is a port of the Data Table components from MDL and has been refactored to play nicely with the rest of RWMC, including themes and sizing. It also adds a couple of features like sticky rows and sticky columns. Enjoy!
