Hi Lucas,
If you are looking at passing a table to Function Import, I don't think its possible.
from you example it looks like your structure Struct1 in ABAP would be
temp NUMC
date SY-DATUM
MeasuredValues - TableType
For ODATA,
You can create three parameters for Func Import - Temp , Date , MeasuredValues ( as string ).
Then from Client you can either pass comma separated values or JSON string in this field MeasuredValues. In your ABAP code you can split the field into a table or use JSON de-searlizer and fill your struct1.
ex - /TestFunct1?Temp='XXXX'&Date='XXXXX'&MeasuredValues='ID1,0111,ID2,002,ID3,003'
Also could you explain your use-case a little more since i dont think you actually need a function import here.

Mayank
