我正试图说明以下几点：
df1型price side timestamp
timestamp
2016-01-04 00:01:15.631331072 0.7286 2 1451865675631331
2016-01-04 00:01:15.631399936 0.7286 2 1451865675631400
2016-01-04 00:01:15.631860992 0.7286 2 1451865675631861
2016-01-04 00:01:15.631866112 0.7286 2 1451865675631866
df2型bid bid_size offer offer_size
timestamp
2016-01-04 00:00:31.331441920 0.7284 4000000 0.7285 1000000
2016-01-04 00:00:53.631324928 0.7284 4000000 0.7290 4000000
2016-01-04 00:01:03.131234048 0.7284 5000000 0.7286 4000000
2016-01-04 00:01:12.131444992 0.7285 1000000 0.7286 4000000
2016-01-04 00:01:15.631364096 0.7285 4000000 0.7290 4000000
与data = pd.concat([df1,df2], axis=1)
但我得到了如下结果：InvalidIndexError Traceback (most recent call last)
