Is there a way to convert table columns and terms into regular numbers?

I made Table set from excel file.

Timeline = readtable('Timeline.xlsx');
Lidar_DeltaT = Timeline(2, 6);
Lidar_Distance= readtimetable('Lidar Cycle.txt');
summary(Lidar_Distance);
Lidar_Distance.Time = Lidar_Distance.Time + seconds(Lidar_DeltaT);

Timeline(2, 6)'s number value is 1

I want to make

"Lidar_Distance.Time = Lidar_Distance.Time + seconds(Lidar_DeltaT);"

line has same meaning of the line

"Lidar_Distance.Time = Lidar_Distance.Time + seconds(1);"

But It occurs an error. What should I do?

You haven't showed us the text of the error, but I'm guessing it was:

Error using seconds (line 19)
Input data must be a real, numeric array.

Using parentheses to index into a table array (like Timeline) returns a smaller table.

Using curly braces to index into a table array returns the contents of those elements of the table.

Using dot to retrieve a variable from a table array returns the contents of that variable.

t = table(123)
s1 = seconds(t(1, 1)) % Throws an error
s2 = seconds(t{1, 1}) % Works
s3 = seconds(t.Var1)  % Also works

If that's not the text of the error, please show the full and exact text of the error (all the text displayed in red in the Command Window.)
