2.1.156 Part 4 Section 2.4.29, right (Table Cell Right Margin Default)
WordPad supports this element. The standard states that this element specifies the amount of space between the right extent of the current cell contents and the right border of all table cells within the parent table (or table row). Furthermore, WordPad applies half of the value of the w attribute as the left margin, and half of the value of the w attribute as the right margin. When both left margin and right margin values are specified, half of the value of each specified margin is calculated, and the sum of the results is used as both left margin and right margin. WordPad supports this element only when the value of the type attribute is "dxa". On save, WordPad writes these margin values as children of the <tcMar> tag instead of children of the <tblCellMar> tag.
