KindEditor 富文本 ctrl+z 会重置元素上的自定义属性怎么解决?

//手写了一个插入带属性的表格的事件，但是组合键会将自定义属性（data-table）去掉，怎么办？
function createTable(attr) {
            let width = attr.tableWidth ? attr.tableWidth + attr.widthUnit : 'auto',
                height = attr.tableHeight ? attr.tableHeight + attr.heightUnit : 'auto',
                border = attr.tableBorder ? attr.tableBorder : '1',
                borderColor = attr.borderColor,
                bgColor = attr.bgColor,
                cellspacing = attr.tableMargin,
                cellpadding = attr.tablePadding,
                align = attr.alignment ? attr.alignment : '';
            let table = `<table class="dataTable" ${align ? 'align=' + align : ''} border="${border}" bordercolor="${borderColor}" style="width:${width};height:${height};background-color:${bgColor}" data-table="${attr.tableSource}" cellspacing="${cellspacing}" cellpadding="${cellpadding}"><tbody>`;
            for (let i = 1; i <= attr.tableRow; i++) {
                table += `<tr>`;
                for (let j = 1; j <= attr.tableCol; j++) {
                    table += `<td>&nbsp</td>`;
                }
                table += `</tr>`;
            }
            table += `</tbody></table>&nbsp`;
            editor.insertHtml(table);
            _body.find('table.dataTable').unbind().on('click', function (e) {
                window.event ? window.event.cancelBubble = true : e.stopPropagation();
                curDataSource = $(this).attr('data-table');
            })
        }
