What problem does this feature solve?

vtable-vue的dataConfig配置项totals动态变更，如何更新，目前不会主动渲染
<PivotTable :options="tableOptions" :records="records" ref="pivotTableRef">

其中tableOptions的dataConfig如下：
dataConfig: { totals: { row: { showGrandTotals: true, showSubTotals: false, subTotalsDimensions: [], grandTotalLabel: 'Row Totals', subTotalLabel: 'Sub Totals' }, column: { showGrandTotals: true, // 总合计列 showSubTotals: true, // 组内合计列 subTotalsDimensions: ['Region'], grandTotalLabel: 'Column Totals', subTotalLabel: 'Sub Totals' } } },

点击事件动态修改showGrandTotals的值，发现vtable不会主动更新，尝试使用vtable实例提供的updateOption并未生效

const handleClick = () => { const show = tableOptions.value.dataConfig.totals.row.showGrandTotals tableOptions.value.dataConfig.totals.row.showGrandTotals = !show }

What does the proposed API look like?

期望可以提供一个update方法可以主动更新图表，update(option) option为当前的option

目前api并没有提供可以更新dataConfig的update方法
