What is a Table?

Fundamentals

A table has two parts: a schema, and a rectangular collection of cells.
A schema is an ordered sequence of column names and sorts.
- Column names must be distinct (no duplicates)
A column name is a string-like first-class value
A sort is a specification of the data that a column contains.
- Each cell in the i-th column must match the i-th sort.
Cells may be organized into rows or columns. Either way:
- All rows must have the same length
- All columns must have the same length
Cells may contain data or may be missing data
