📜 Issue description:

Suppose I have the following markdown tables:

Column A | Column B
-------- | --------
1        | 2
3        | 4


| Column A | Column B |
| -------- | -------- |
| 1        | 2        |
| 3        | 4        |

The first table (without the leading and trailing pipes) doesn't render correctly:

However, this is a common format for markdown tables. For example, see: PHP Markdown Extra and Python Markdown (used by MkDocs). It's also supported in GitHub Markdown.

📑 Reproduction steps:

1. neovim -u minit.lua test.md
2. Paste the text above
3. Press Escape to switch to normal mode to see the preview

💻 Minimal init:

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
    spec = {
        {
            "nvim-treesitter/nvim-treesitter",
            build = ":TSUpdate",

            ensure_installed = { "html", "latex", "markdown", "markdown_inline", "typst", "yaml" }
        },
        {
            "OXY2DEV/markview.nvim",
            -- branch = "dev",
            lazy = false
        }
    },
});

Both tables would render correctly.
