bug: Tables don't render correctly if the pipe at the end of line is missing

使用报告中所示的 Markdown 表格和提供的 pipe_table 配置在 Neovim 中复现该问题，然后跟踪 plugin 如何识别没有尾随 pipe 的表格。当示例能够正确渲染，同时保留现有的表格行为时，即视为完成；如果项目有针对性的回归测试，请添加或运行该测试。

Describe the bug

Tables are not rendered correctly if the trailing pipe is omitted.
From GitHub-flawored markdown spec (common mark doesn't have tables):

A leading and trailing pipe is also recommended for clarity of reading, and if there’s otherwise parsing ambiguity.

Recommended - not required.

I usually omit the trailing pipes - the tables look ok in plain text without inserting dozens of empty spaces to align the right border.

Table like this should be valid and render correctly.
It looks good in plain text, without a need to insert dozens of spaces

| state  | dscription
|--------|---
| open   | port is accessible, and service is listening
| closed | port is accessible, but no service is listening

Expected behavior

Tables without a trailing pipe should be rendered correctly.
