Bug 1730442 - part 6: Make HTMLEditor::InsertTableColumnsWithTransaction() collect all necessary data before touching the DOM tree r=m_kato
It needs to work with the latest layout information to consider which cell element is the insertion point due to rowspan and colspan. Therefore, this patch makes it collects all cell data before touching the DOM except the case that it needs to normalize the table to make it rectanble. Note that the case requiring the normalizer should be fixed in a later patch. This method is corresponding to an XPCOM method. Therefore, this is tested by `test_nsITableEditor_insertTableColumn.html`. And also it's used by the inline table editor, but we don't have automated tests for this because of no API to get the buttons. Therefore, I tested it by my hand. Note that the old code fails to put caret to newly inserted cell at the reftest situation. This fixes the bug too. Therefore, this changes the reftest's reference.
