不论执行ftable-fill还是ftable-reformat，都会提示：
Symbol’s function definition is void: valign-box-char
不知道问题出在哪里，是不是配置错误？

我的配置如下：
(use-package ftable
:quelpa ((ftable :repo "casouri/ftable" :fetcher github) :upgrade t)
:init
(require 'ftable)
:custom
(ftable-fill-column 20))

相应的，我也有使用你写的valign，配置如下：
(use-package valign
:quelpa ((valign :repo "casouri/valign" :fetcher github) :upgrade nil)
:config
(setq valign-fancy-bar t)
:hook
((org-mode . valign-mode)))

Hello, thanks for your package, this was a feature a was looking for.

When I create a table with default horizontal lines like |----+-----+----| your ftable--table-info return tablep = nil. Editing horizontal lines like in your readme +----+-----+----+ solves the problem but I need to edit them manually every time.

Setting ftable-box-charset-alist variable will solve this issue probably but I wanted to open this PR to know why you use custom hlines. Is there any way to change how org inserts hlines?
