Function generateCreateTableSource

generateCreateTableSource(
schema: ObjectSchemaBuilder<any, any, any, any, any, any, any>,
): { down: string; up: string }
Generate up and down TypeScript code strings (4-space-indented\n * fragments) for creating a table from a schema.

Unlike generateCreateTable (which returns a Knex callback), the output is plain source text suitable for writing into a migration file. The fragments are designed to be embedded directly inside up() / down() functions.
Parameters
- schema: ObjectSchemaBuilder<any, any, any, any, any, any, any>
  An ObjectSchemaBuilder with .hasTableName() and column DDL extensions.
Returns { down: string; up: string }
{ up, down } source fragments.
Example
```
const { up, down } = generateCreateTableSource(UserSchema);
// up:  "    await knex.schema.createTable('users', (table) => { … });"
// down: "    await knex.schema.dropTableIfExists('users');"
```
