// (1) Borders with the 'border-style' of 'hidden' take precedence over all
// other conflicting
// borders. Any border with this value suppresses all borders at this
// location.
// (2) Borders with a style of 'none' have the lowest priority. Only if the
// border properties of all
// the elements meeting at this edge are 'none' will the border be omitted
// (but note that 'none' is
// the default value for the border style.)
// (3) If none of the styles are 'hidden' and at least one of them is not
// 'none', then narrow borders
// are discarded in favor of wider ones. If several have the same
// 'border-width' then styles are preferred
// in this order: 'double', 'solid', 'dashed', 'dotted', 'ridge', 'outset',
// 'groove', and the lowest: 'inset'.
// (4) If border styles differ only in color, then a style set on a cell
// wins over one on a row,
// which wins over a row group, column, column group and, lastly, table. It
// is undefined which color
// is used when two elements of the same type disagree.
