示例1: PreCoalesceTable
// <Summary>
// Table column handling. RTF tables allow each row to be arbitrarily aligned. XAML (like HTML)
// doesn't allow that. You can achieve that effect in HTML by inserting extra rows with spurious
// cells propped to a specific width, but I'm not going to do that. Instead, I'm going to split
// the rows into separate tables when combining some set of rows into a table would force me
// to fabricate a column that doesn't contain any defined cell.
// </Summary>
private int PreCoalesceTable(DocumentNode dn)
{
int nInserted = 0;
int nAt = dn.Index;
ColumnStateArray cols = dn.ComputeColumns();
// OK, now I have a set of columns and information about which row caused the column to
// be instantiated. The naive algorithm is to strip the first N rows from the table until
// the row that caused an uninstantiated column, break the table there, and then run the
// algorithm again on the trailing table.
int nUnfilledRowIndex = cols.GetMinUnfilledRowIndex();
if (nUnfilledRowIndex > 0)
{
// OK, Need to insert a new table and table group around the remaining rows.
