这不是 BUG,和 table 也没有关系,通过 JS 修改值时不会触发事件。可以参考下面两个解决方案

  1. 使用 input-affix 事件
form.on('input-affix(input-num-demo)', function (data) {
  console.log(data.elem.value);
});
  1. 将这段代码放到你的公共模块,引入页面中
      var props = Object.getOwnPropertyDescriptor(
        HTMLInputElement.prototype,
        'value'
      )
      Object.defineProperty(
        HTMLInputElement.prototype,
        'value',
        $.extend({}, props, {
          set: function (v) {
            var oldv = this.value
            props.set.call(this, v)
            this.dispatchEvent(new CustomEvent('input'))
            if (oldv !== v) {
              this.dispatchEvent(new CustomEvent('change'))
            }
          },
        })
      )
