Rearrange the rows as column variables

I have a large txt file with 41MB. It consists of 72 sensors measurements over the time. In case, I want to rearrange the table so that the 72 sensors are set as the column headings while the change of the "R" values of each of the sensors are shown under each column. For each row, the recording time of the #0 sensor will be put as each time step.
The resulting table would be like this:
As the file is too large and cannot be attached, below I show the first 3 sets of 72 sensor measurements. There are more than 10,000 sets in total. Thank you in advance.

If I understand correctly, you only need the times corresponding to sensor #0, and the other times can be discarded/ignored. If that's the case, maybe something along these lines will work for you:
t = readtable('table.txt','PreserveVariableNames',true);
N_sensors = 72;
zero_times = t{t{:,'#'} == 0,'Time'};
R = num2cell(reshape(t.R,N_sensors,[]).',1);
t_new = table(zero_times,R{:},'VariableNames',['Time',sprintfc('%d',0:N_sensors-1)])

Did you try readtable
t = readtable('dataTable.txt')
It doesn't look like for each unique time there are 72 readings, so what do you plan on doing about that?
