A feature I want, that appearenly was attempted by some browsers but never stanardized. I want to be able to make a table that can responsively fill out columns.

    +-------+------------+  +-------+------------+  +-------+------------+
    | state | population |  | state | population |  | state | population |
    +=======+============+  +=======+============+  +=======+============+  
    |  AL   | ....       |  |  DE   | ....       |  | MI    | ....       |
    |  AK   | ....       |  |  FL   | .....      |  | MN    | ....       |
    |       |            |  |       |            |  |       |            |  

I need to put the heading at the top. It needs to make the heading sticky. As it is those, AFAIK there is no "easy" solution for this
