Insert Block Into Inline Beside Ex Spanner Table Column

With a multicol container that has a block and with a spanner inside, do the following:

1. Insert an inline right before the spanner
2. Turn the spanner into a table-column
3. Insert an inline child into the previously inserted inline
4. Set column-span:none on the ex-spanner (now table-column)
5. Insert a block into the previously inserted inline child
