                        return k === key
                    });

                    if (!col || !col.width) {
                        return h('th', { ...restProps }, [...children])
                    }

                    const dragProps = {
                        key: col.dataIndex || col.key,
                        class: 'table-draggable-handle',
                        attrs: {
                            w: 10,
                            x: col.width,
                            z: 1,

                            draggable: true,
                            resizable: false
                        },
                        on: {
                            dragging: (x, y) => {
                                col.width = Math.max(x, 10);//留出空白
                            }
                        }
                    };
                    restProps.attrs.widh = col.width;
                    const drag = h('vue-draggable-resizable', { ...dragProps });
                    return h('th', { ...restProps, class: 'resize-table-th' }, [...children, drag])
                }
            },
        };
    },
    methods: {
        setRowKey(record, index) {
            return index;
        }
    }
};
</script>

<style lang="less">
.resize-table-th {
    position: relative;
    .table-draggable-handle {
        height: 100% !important;
        bottom: 0;
        left: auto !important;
        right: -5px;
        cursor: col-resize;
        touch-action: none;
        transform: translate(0px, 0px) !important;
        position: absolute;
        top: 0;
    }
}
</style>

原有的样式文件没有使用的必要，个人添加的部分样式内容就符合需求了
