Lv table update and delete a row

How to upate all cells when a button is pressed?

	rows = lv_table_get_row_cnt(db_table);

	for (uint16_t row = 0; row < rows; row++)
		lv_table_add_cell_ctrl(table, row, 0, LV_TABLE_CELL_CTRL_CUSTOM_1); // Set custom flag

I have tried using: lv_event_send(table, LV_EVENT_REFRESH, NULL);

How to delete a row from the table?

Best regards,
