Suggestion: add a divider option so can separate different rows

[bcastillo-2022474]

hey, It would be great if you could create add a divider between rows, that way we can for example add the sum of a column below each respective column and separate it with a divider. example:

| xi  | fi | fa | xi*fi | xi-media | (xi-media)^2 | fi*(xi-media)^2 | fg   | fr   | fr% |
|-----|----|----|-------|----------|--------------|-----------------|------|------|-----|
| 160 | 5  | 5  | 800   | 7.32     | 53.5824      | 267.912         | 72.0 | 0.20 | 20  |
| 163 | 3  | 8  | 489   | 4.32     | 18.6624      | 55.9872         | 43.2 | 0.12 | 12  |
| 166 | 2  | 10 | 332   | 1.32     | 1.7424       | 3.4848          | 28.8 | 0.08 | 8   |
| 169 | 6  | 16 | 1014  | 1.68     | 2.8224       | 16.9344         | 86.4 | 0.24 | 24  |
| 172 | 9  | 25 | 1548  | 4.68     | 21.9024      | 197.1216        | 129.6| 0.36 | 36  |
|-----|----|----|-------|----------|--------------|-----------------|------|------|-----|
| 830 | 25 | 64 | 4183  | 19.32    | 98.712       | 541.44          | 360  | 1.00 | 100 |

you can see here that below every column I have the sum of that column. what I would like to be able to do is to add a divider, so I can separate the data visually, like I have it in my example

You can add a separator to the penultimate row only e.g.

import { Table } from "console-table-printer";

const table = new Table();
table.addRow({ amount: 1, name: "Apple" });
table.addRow({ amount: 2, name: "Pear" });
table.addRow({ amount: 3, name: "Banana" }, { separator: true });
table.addRow({ amount: 6, name: "Total" });
table.printTable();

Produces:

┌────────┬────────┐
│ amount │   name │
├────────┼────────┤
│      1 │  Apple │
│      2 │   Pear │
│      3 │ Banana │
├────────┼────────┤
│      6 │  Total │
└────────┴────────┘
