tables import/export function

Is your feature request related to a problem? Please describe.

Would be possible to have an export/import table command? I'm trying to have a backup/snapshot only for a given table

Describe the solution you'd like

It would be useful for backup/snapshoting without doing some could thing like saving a part of the tables from mariadb.

Describe alternatives you've considered

Saving and filtering all:

oc_tables_columns
oc_tables_contexts_context
oc_tables_contexts_navigation
oc_tables_contexts_page
oc_tables_contexts_page_content
oc_tables_contexts_rel_context_node
oc_tables_favorites
oc_tables_log
oc_tables_row_cells_datetime
oc_tables_row_cells_number
oc_tables_row_cells_selection
oc_tables_row_cells_text
oc_tables_row_cells_usergroup
oc_tables_row_sleeves
oc_tables_rows
oc_tables_shares
oc_tables_tables
oc_tables_views

but is problematic, and doing this only for an user makes it impossible to import

Additional context

No response

No files, tests, or entry points are identified. Begin by clarifying the proposed export/import command and its scope for a single table, using the MariaDB-backed table list in the issue as an example. Done means a defined, reversible table-only backup and import workflow, with tests identified during investigation.
