A table with no outside border, but internal borders, does not render correctly

[SVendittelli]

Describe the bug
When rendering a table with no outside borders (i.e. top, bottom, left, and right are disabled) and internal borders enabled (i.e. row and column are enabled), the borders do not align correctly. Extra characters are rendered for the horizontal borders.

Setup
Please complete the following information along with version numbers, if applicable.

• OS: Windows 11
• Shell: PowerShell 7.4.4, git bash
• Terminal Emulator: Alacritty, Windows Terminal, Git Bash
• Terminal Multiplexer: N/A
• Locale: en_GB.UTF-8

To Reproduce
Steps to reproduce the behavior:

1. Create a new go module (mkdir table && cd table && go mod init table)
2. Create a main.go with the contents below
3. Run go get . to pull dependencies
4. Run go run .
5. Observe incorrect rendering:

1│2│3
├─┼─┼─┤
4│5│6
├─┼─┼─┤
7│8│9

Source Code
main.go

package main

import (
	"fmt"

	"github.com/charmbracelet/lipgloss"
	"github.com/charmbracelet/lipgloss/table"
)

func main() {

	board := [][]string{
		{"1", "2", "3"},
		{"4", "5", "6"},
		{"7", "8", "9"},
	}

	t := table.New().
		Border(lipgloss.NormalBorder()).
		BorderRow(true).
		BorderColumn(true).
		BorderTop(false).
		BorderBottom(false).
		BorderLeft(false).
		BorderRight(false).
		Rows(board...)

	fmt.Println(t.Render())
}

Expected behavior
The additional characters (├ and ┤) would not be rendered, resulting in:

1│2│3
─┼─┼─
4│5│6
─┼─┼─
7│8│9
