What is an efficient way to assign values from one table (many rows and columns) to a table with one row.
Table 1: 3 variables with 10 entries each (10 rows x 3 columns) - VarNames: Start, End, Time & all values are numbers
Table 2: I want to extract data from Table 1 and input the values into Table 2 - VarNames: Start1, End1, Time1, Start2, End2, Time2, ... Start10, End10, Time10
For example:

The goal is to create something like below so that every column in Table2 doesn't need to have its own line of code; but I'm not sure if that's possible or realistic to do.
T2 = table();
x = 1;
while x<11
T2.Start(x) = T1(x,1);
T2.End(x) = T1(x,2);
T2.Time(x) = T1(x,3);
x = x+1;
end

A bit convoluted, but should work.
% Create first table
Start = (11:10:101)';
End = Start+1;
Time = End+1;
T1 = table(Start,End,Time)
% Turn table into an array and transpose
d = table2array(T1)'
% create new variable names
varnm = ["Start";"End";"Time"] + (1:length(d));
% Build new table
T2 = array2table(d(:)','VariableNames',varnm(:))

Concatenate the two tables.
% First table
ParticipantNum = 1;
TrialNum = 15;
AvgTime = 7;
T1 = table(ParticipantNum,TrialNum,AvgTime)
% Second table
Start1 = 1;
End1 = 2;
Time1 = 3;
T2 = table(Start1,End1,Time1)
% Concatenate the tables together (must have same number of rows)
T3 = [T1,T2]
