| ------- | ----- | ------------ |
| Coffee  | 4     | /= B2 * 0.08 |
| Bagel   | 3     | /= B3 * 0.08 |

Bare A1-style identifiers inside a formula resolve to the same table.

Naming a table

### Budget

| Category | Amount |
| -------- | ------ |
| Rent     | 1500   |
| Food     | 600    |

/= sum(@Budget:B2:B3)       // → 2100

H3 → global; H4 → module-local.

Cell references from text blocks

@Budget                     // whole table → 2D array
@Budget:A1                  // single cell
@Budget:A2:B5               // rectangular range
@Budget[A2:B5]              // alternative range syntax
@Calculations::Revenue:B1   // cross-block

Mutation

@Budget:C2 = "subtotal"
@Budget:C3 = sum(@Budget:B2:B5)

Statement-form only.

Persistence

Markdown is always maintained as the front-facing document content. But the actual file has a lot more in it, it carries metadata, positional information, graphics properties, etc. Feel free to inspect it, it's base64 binary data; A zip file appended to the end of the markdown document. Invisible to a standard text editor, so it's still editable and sharable externally without losing the depth of information Acord keeps or breaking compatibility with external markdown editors/renderers. There's enough custom file extension formats out there already. No need for a new one for this.

Is how it will look if you inspect the raw file. If you are curious (and it's kinda neat!) check out one of the notes with Hex Fiend or another simnilar program ;D
