| 接下来计算 `columnOrdinalMap` ，首先判断是否需要打印时间戳，如果需要则将时间戳记录为第一列。 | ||

| 然后遍历表头中的列名列表，并检查 `columnNameIndex` 是否被初始化，该字段来源于去重时计算的 `pathToIndex`，记录了每个时间序列路径在查询中的位置。如果被初始化，则其中的位置 + 2 即为在结果集中的位置；未被初始化则按顺序记录位置即可。 |

If columnNameIndex is not initialized, the logic of generating columnOrdinalMap is same as deduplicate column in the server.
