3.3.1: Visual editor loses merged table cells on save (no ^^ / || written)

[andy-vdg]

Version: 3.3.1 (Docker), PostgreSQL; markdown editor settings default (multimdTable on)

What happens

Cells merged in the Visual editor are not kept on save. The saved markdown leaves out the covered cells and has no MultiMarkdown span markers (^^ for rows, || for columns). The rendered page therefore shows short rows and no merge.

Steps

1. Create a page with the Visual editor and insert a 3-column table with three body rows.
2. Merge the last column of all body rows into one cell (merge cells), and type Shared into it.
3. Save and view the page.

Saved markdown:

| A | B | C |
| --- | --- | --- |
| 1 | x | Shared |
| 2 | y |
| 3 | z |

Rendered HTML:

<tr><td>1</td><td>x</td><td>Shared</td></tr>
<tr><td>2</td><td>y</td></tr>
<tr><td>3</td><td>z</td></tr>

There is no rowspan, and rows 2 and 3 are missing a cell.

Expected: the merge survives the round trip. The renderer already supports it, because this markdown renders a correct rowspan/colspan:

| A | B | C |
| --- | --- | --- |
| 1 | x | Shared |
| 2 | y | ^^ |
| wide || q |

Where it seems to come from: the table serializer writes only the cells present in each row and never emits ^^ or an empty colspan cell.
