* lisp/textmodes/table.el: Use lexical-binding, dolist, define-minor-mode.
(table-initialize-table-fixed-width-mode) (table-set-table-fixed-width-mode): Remove functions. (table-command-list): Move initialization into declaration. (table--tweak-menu-for-xemacs): Move defun outside mapcar. (table-with-cache-buffer): Use `declare'. (table-span-cell): Simplify via CSE. (table-fixed-width-mode): Use define-minor-mode. (table-call-interactively, table-funcall, table-apply): Remove. (table-function): New function, to replace them.
