我想创建一个像这样的表
trends = ['Bill','Visits', 'Avg. Visits','abc',
'mcd', 'mckfd', 'mfd', 'aps', 'mvmv', 'dep']
df_new = df.loc[df.index.repeat(len(trends))].assign(trend_type=trends * len(df))
print(df_new)
id email trend_type
0 1 abc@xyz.com Bill
0 1 abc@xyz.com Visits
0 1 abc@xyz.com Avg. Visits
0 1 abc@xyz.com abc
0 1 abc@xyz.com mcd
0 1 abc@xyz.com mckfd
0 1 abc@xyz.com mfd
0 1 abc@xyz.com aps
0 1 abc@xyz.com mvmv
0 1 abc@xyz.com dep
1 2 cdsm@kcmd.com Bill
1 2 cdsm@kcmd.com Visits
1 2 cdsm@kcmd.com Avg. Visits
1 2 cdsm@kcmd.com abc
1 2 cdsm@kcmd.com mcd
1 2 cdsm@kcmd.com mckfd
1 2 cdsm@kcmd.com mfd
1 2 cdsm@kcmd.com aps
1 2 cdsm@kcmd.com mvmv
1 2 cdsm@kcmd.com dep
我找不到定义在DAX Table中使用的变量的方法。有什么建议吗？
