| 841 | * In a wikitext-syntax-table-parsing context, the meaning of |
| 842 | * "|", "||", "!", "!!" is context-sensitive. Additionally, the |
| 843 | * complete syntactical construct for a table cell (including leading |
| 844 | * pipes, attributes, and content-separating pipe char) might straddle |
| 845 | * a template boundary - with some content coming from the top-level and |
| 846 | * some from a template. |
| 847 | * |
| 848 | * This impacts parsing of tables when some cells are templated since |
| 849 | * Parsoid parses template content independent of top-level content |
| 850 | * (without any preceding context). This means that Parsoid's table-cell |
| 851 | * parsing in templated contexts might be incorrect |
| 852 | * |
| 853 | * To deal with this, Parsoid implements this table-fixups pass that |
| 854 | * has to deal with cell-merging and cell-reparsing scenarios. |
| 855 | * |
| 856 | * HTML-syntax cells and non-templated cells without any templated content |
| 857 | * are not subject to this transformation and can be skipped right away. |
| 858 | * |
| 859 | * FIXME: This pass can benefit from a customized procsssor rather than |
| 860 | * piggyback on top of DOMTraverser since the DOM can be significantly |
| 861 | * mutated in these handlers. |
