This patch do following things: 1. Create nsDisplayTableBorderCollapse that draws all collapse border of table. 2. Don't use nsDisplayTableBorderBackground. 3. Let column and column group frame generate display items. 4. When traversing the table, also traverse the column and column group frames. 5. For each type of table frame (col group, col, row group, row and cell), draw their own background. MozReview-Commit-ID: 1s2VLv6G8xi
