# Freight & Cargo Services block

> Freight lane matrix with headhaul and backhaul split cells, a path to both edges and a lane modal

Origin by destination matrix for a road freight network across 12 European countries: each cell splits the headhaul, coloured by margin band, from the backhaul, with a lane modal, totals and repricing. ReUI DataGrid, Filters, Cascader, Timeline.

## Best for

Pricing teams finding losing freight lanes in a split-cell matrix, reading each lane and its backhaul, then repricing

## Agent notes

- Swap `TERMINALS`, `SHIPPERS` and `RATE_HISTORY` in data.ts; `seedLanes` only builds the demo `LANES`, so load your own lane list
- `bandOf` sets the bands, `figuresOf` the lane economics, `formatCellFigure` the cell halves; rates and costs are per loaded km, from `kmBetween`
- `useLaneStore` changes only React state; send `createLane`, `updateLane`, `closeLane` and `reprice` to your API

## When not to use

- Store P&L by geography with plan attainment and a tree of markets: use [Regional Store P&L](https://reui.io/blocks/data-grid/advanced/data-grid-advanced-2.md) (`get_block("data-grid-advanced-2")`)

## About Advanced blocks

### When to use

- Reporting tables whose rows carry in-cell bars, sparklines or heat cells beside the figures
- Performance reviews that weigh each record against a target, a plan or a prior period
- Review queues and record lists with create, edit, delete and undo, each row opening a tabbed sheet

### When not to use

- A rule builder on its own, to narrow a list or table you already have: use [Filters](https://reui.io/components/filters.md) (`get_component("filters")`)
- A plain sortable table of text cells, assembled from parts in your own layout: use [Data Grid](https://reui.io/components/data-grid.md) (`get_component("data-grid")`)
- Values typed into the cells themselves, with validation and a save or discard bar: use the [Editing blocks](https://reui.io/blocks/data-grid/editing.md)

### Agent notes

- Rows live in a client store hook whose `create`, `update` and `remove` change only browser state; back them with your API
- Search, filters and sort run in the browser over every row before `useTable` sees them; move that query to your API at scale
- Each page.tsx wraps the block in a `min-h-svh` main with padding, a `max-w-7xl` width and an sr-only `h1`; drop that wrapper inside an app shell

Every ReUI item has a twin like this one; the index is https://reui.io/llms.txt. Agents with the ReUI MCP (https://reui.io/docs/mcp) get the same guidance from the getters named above.
