Table: Possible to enable all borders around headings but only vertical borders around body?

The effect I want is this:

I can't see a way of changing the border chars for individual Rows/Cells (only enabling/disabling the border entirely), and in any case that still wouldn't have the desired effect, as I want the body rows to be compact, i.e. no additional newline is inserted between each row.

I'm currently using this hack:

import { Table, border as defaultBorder, type Border } from 'jsr:@cliffy/table@1.0.0-rc.7'
import { regExpEscape } from 'jsr:@li/regexp-escape-polyfill@0.3.4'

const r: typeof String.raw = (s, ...vals) => String.raw(s, ...vals.map(regExpEscape))

function table(header: string[], body: string[][], border: Border = defaultBorder) {
    const { leftMid, mid, midMid, rightMid } = border
    const replacer = new RegExp(r`\n${leftMid}(?:${mid}|${midMid})+${rightMid}`, 'g')
    let rowIdx = 0

    return new Table()
        .chars(border)
        .border()
        .header(header)
        .body(body)
        .toString()
        .replace(replacer, (m) => rowIdx++ ? '' : m)
}

Is there a way of doing this that doesn't involve constructing a custom regex like this though?
