// @access public
// @content Includes a block of styles for sticky data tables that sets table max-width, max-height and column min-width
// @example - @include sticky-header($max-height: rem(900px), $min-width: rem(30px));
// @param {value} $max-width [100%] - sets the max-width of the data table parent container
// @param {value} $max-height [rem(300px)] - sets the max-height of the data table
// @param {value} $min-width [rem(100px)] - sets the min-width of th's and td's so their sizes align
