17.6.2 (The collapsing border model) says:

  # The diagram below shows how the width of the table, the widths
  # of the borders, the padding, and the cell width interact. Their
  # relation is given by the following equation, which holds for
  # every row of the table:
  #
  #    row-width = (0.5 * border-width_0) + padding-left_1 +
  #                 width_1 + padding-right_1 + border-width_1 +
  #                  padding-left_2 +...+ padding-right_n +
  #                   (0.5 * border-width_n)
  #
  # Here n is the number of cells in the row, padding-left_i and
  # padding-right_i refer to the left (resp., right) padding of
  # cell i, and border-width_i refers to the border between
  # cells i and i + 1.

But what does "the border between cells i and i + 1" actually refer to?

Simon Sapin thinks that the border conflict resolution needs to happen before
the layout, so that there is only one border between cells i and i+1 by the
time we care about it.
