/**
 * Table data processing pipeline. TablePipeline provides context and helper methods used during table data processing, including:
 *
 * 1. ctx: the context object. A step (a stage in the pipeline) can read/write fields on ctx.
 *    Some field names in ctx have special meanings (for example, primaryKey represents the row primary key);
 *    avoid using these names for custom context fields.
 *
 * 2. rowPropsGetters: a queue of getRowProps callbacks. A step can append callbacks via pipeline.appendRowPropsGetter;
 *    when calling pipeline.getProps(), the queued functions are combined to form the final getRowProps.
 *
 * 3. Current pipeline state: dataSource, columns, and rowPropsGetters.
 *
 * 4. Snapshots: calling pipeline.snapshot(name) records the current state, which can be retrieved later by name.
