el-table一格两行；概率；find

样式：

根据概率表头关键代码：rateRanges；
scope.row.targetHitTable.find((target:any) =>
target.targetHitRate >= range.min && target.targetHitRate <= range.max)!.targetHitNum
（1）!.是TypeScript中的非空断言操作符。非空断言告诉编译器，这个表达式的结果不会是null或undefined，避免编译时的类型检查错误。
（2）scope.row.targetHitTable.find(…) 是在targetHitTable数组中查找满足条件的对象 。
（3）条件是targetHitRate在某个区间内，这里range.min和range.max是当前列的区间范围。找到后，访问该对象的targetHitNum属性。
一格两行关键：:span-method=“objectSpanMethod”
表格内容居中关键：:cell-style=“{ textAlign: ‘center’ }” :header-cell-style=“{ ‘text-align’: ‘center’ }”
