/// The table:border-model attribute specifies what border model to use when creating a table
/// with a border.
///
/// The defined values for the table:border-model attribute are:
/// • collapsing: when two adjacent cells have different borders, the wider border appears as
/// the border between the cells. Each cell receives half of the width of the border.
/// • separating: borders appear within the cell that specifies the border.
///
/// In OpenDocument, a row height or column width includes any space required to display borders
/// or padding. This means that, while the width and height of the content area is less than the
/// column width and row height, the sum of the widths of all columns is equal to the total width of the
/// table.
