How should dates be aligned in a table?

Dates (in any format) should ideally be left-aligned inside a data table column. A rule of thumb is: integers should be right aligned, while other types of data should be left aligned. The default alignment for most types of data is left alignment -- this helps make the data easily scannable, readable and comparable.

What does the grid is aligned mean?

Aligning two or more grids means columns will be kept aligned in all grids. In other words, column changes to one grid (column width, column order, column visibility etc) are reflected in the other grid.
