CJK characters cause table column misalignment

[MichaelC001]

Description

When rendering markdown tables containing CJK (Chinese/Japanese/Korean) characters, the column borders become misaligned. The plugin calculates CJK characters as width 1 instead of width 2 (their actual display width in monospace fonts).

Screenshots

Markdown Source

| 类型     | 方法                       | 效果     |
|----------|----------------------------|----------|
| Forward  | e.concat(this._dataList)   | 左边显示 |
| Backward | this._dataList.concat(e)   | 右边显示 |

Problem

• CJK characters have display width of 2 in monospace fonts
• The plugin calculates them as width 1
• This causes the right border | to shift left
• My font renders CJK and ASCII correctly aligned - this is not a font issue, but a width calculation issue in the plugin

Expected Behavior

Table borders should align correctly. The plugin should use vim.fn.strdisplaywidth() or similar to calculate actual display width instead of byte length or character count.

terminal shows good this is what neovim shows
