How can I store a table as time series in which particular column of table has a an array as entry?

I want to create a timeseries from the data I have recorded from some sensors. Data is in the form of table with several columns. One particular column as array of values. For example:

Data1 Data2 Data3

1.2 1.5 0.45, 0.345, 0.73

1.4 1.7 0.4, NaN, 023

How can I create timeseries from such data?

Hi. Can you give an example what exactly you want as output?
