Make the title column of the table stretchable left and right jquery plug-in package_jquery

/*
Written by mlcactus, 2014-11-24
This is a jquery plug-in that I packaged, which enables each column of the table to stretch left and right, thereby making the width smaller or larger
Usage:
Single table: $("#table_id").tableresize();
All tables on the page: $("table").tableresize();

$.fn.tableresize = function () {
        var _document = $("body");
