+If the `layout` option is set to
+- `fluid`, then this value doesn't have any effect
+- `fixed`, then this value is set in pixels
+- `ratio`, then this value works similar to `flex` property in CSS. So, if column A has `width: 1` and column B has `width: 2`, then column B will occupy twice as much width as column A
