Fix typo in examples of the table command (#15925)

# Description

Currently, the examples for `table` have a small typo (notice row 1,
column a):
```
  Render data in table view
  > [[a b]; [1 2] [3 4]] | table
  ╭───┬───┬───╮
  │ # │ a │ b │
  ├───┼───┼───┤
  │ 0 │ 1 │ 2 │
  │ 1 │ 3 │ 4 │
  ╰───┴───┴───╯

  Render data in table view (expanded)
  > [[a b]; [1 2] [2 [4 4]]] | table --expand
  ╭───┬───┬───────────╮
  │ # │ a │     b     │
  ├───┼───┼───────────┤
  │ 0 │ 1 │         2 │
  │ 1 │ 3 │ ╭───┬───╮ │
  │   │   │ │ 0 │ 4 │ │
  │   │   │ │ 1 │ 4 │ │
  │   │   │ ╰───┴───╯ │
  ╰───┴───┴───────────╯

  Render data in table view (collapsed)
  > [[a b]; [1 2] [2 [4 4]]] | table --collapse
  ╭───┬───╮
  │ a │ b │
  ├───┼───┤
  │ 1 │ 2 │
  ├───┼───┤
  │ 3 │ 4 │
  │   ├───┤
  │   │ 4 │
  ╰───┴───╯
  ```

I changed the example commands to match their outputs, and swapped the 2 for a 3 in all the following examples too, for consistency.
