Create a new table from a plot constructed from data points

Dear all,
Reading an excel sheet with around 24000 data points, I made a plot. Now I would like to create a new table from this plot with a user-defined interval, let say with only 10 data points. Is it possible to do so in Matlab?
Many thanks in advance.

% a table with 1000 rows:
t = table((1:1000).',2*(1:1000).'+100,'VariableNames',{'x' 'y'})
% user-defined interval over x:
x_limits = [200 209];
% logical index saying whether each x in the table is within the interval:
idx = t.x >= x_limits(1) & t.x <= x_limits(2);
% new table with x and y but only where x is within the interval:
new_t = table(t.x(idx),t.y(idx),'VariableNames',{'x' 'y'})
