pub const CELL_IN: &str = "cell-in";Expand description
The wrapper every cell and heading holds its contents in.
The column is a flex item that may close to nothing, and padding cannot shrink, so the padding lives on this and the column clips it. It is also what a droppable column hides when it is under its floor, and where the type goes, so a heading and the cells under it are the same box whatever each holds.
