/**
 * Given original matrix like this:
 * [
 *   ['🍉', '🍒', '🍌'],
 *   ['🦁', '🦄', '🐼'],
 *   ['🍕', '🍿', '🍔'],
 * ]
 * console.table() prints:
 * | (index) |  0   |  1   |  2   |
 * --------------------------------
 * |    0    | '🍉' | '🍒' | '🍌' |
 * |    1    | '🦁' | '🦄' | '🐼' |
 * |    2    | '🍕' | '🍿' | '🍔' |

 * We would like to get the original array from this latter string.
 *
 * @param {string} str - The output of console.table()
 * @return {string[][]} 2d array
