One way, using the exact equation you posted:
syms x t
a = 4.2; % Use Appropriate Value
u(x,t) = t+sin(x-a*t);
figure
fsurf(u, [- pi pi 0 1])
and another possibility:
x = linspace( ... ); % Create Vector
t = linspace( ... ); % Create Vector
[X,T] = ndgrid(x,t);
u = @(x,t) t+sin(x-a.*t);
figure
mesh(X, T, u(X,T))
grid on
.

There appears to be missing data. I cannot guess what they are.
Try this:
x = linspace(-2*pi, 2*pi, 25); % Create Vector
t = linspace(-2*pi, 2*pi, 25); % Create Vector
a = 1;
[X,T] = ndgrid(x,t);
u = @(x,t) t+sin(x-a.*t);
figure
plot(t, u(X,T))
hold on
plot(t, x, 'k', 'LineWidth',2)
hold off
grid on
That is as close as I can get.
Experiment with the code to get the result you want.
