TypeScript commutable.appendCellToNotebook函数代码示例

/**
 * Creates a dummy notebook for Redux state for testing.
 *
 * @param {object} config - Configuration options for notebook
 * config.codeCellCount (number) - Number of empty code cells to be in notebook.
 * config.markdownCellCount (number) - Number of empty markdown cells to be in notebook.
 * config.hideAll (boolean) - Hide all cells in notebook
 * @returns {object} - A notebook for {@link DocumentRecord} for Redux store.
 * Created using the config object passed in.
