Issue Summary

Converting pages containing tables that incude a numberingColumn from the Legacy to the Cloud editor causes any data contained in the numbered column to be lost. The first column (numberingColumn) is auto-numbered, and any content in those cells is overwritten.

Steps to Reproduce

1. In a legacy editor page, create a table with a numberingColumn as the first column and include data in the numbered cells.
2. Migrate to Cloud and confirm the data persists in the legacy editor version.
3. Convert the page to the new Cloud editor.

Expected Results

Numbered cells are converted preserving the additional data.

Actual Results

Observe that the first column now only shows numbers, and the previously existing data is no longer available

Workaround

1. Restore the legacy version of the page.
2. Enter edit mode using the legacy editor.
3. Duplicate the numbering table column by copying it then pasting it (either through CTRL+C and CTRL+V, or through the table editing toolbar).
4. Deselect “Insert numbering column” in the table settings (the rightmost button in the table editing toolbar).
5. Publish and convert the page to the new editor.
