Question: Coordinates of point with a Data Table

I'm doing this interactive component and for coordinates of points I use one TextArea for each coordinate.

a:= Do(%CB);

x1:=Do (%x1);
y1:=Do (%y1);
x2:=Do (%x2);
y2:=Do (%y2);
x3:=Do (%x3);
y3:=Do (%y3);
x4:=Do (%x4);
y4:=Do (%y4);
x5:=Do (%x5);
y5:=Do (%y5);

#x6:=Do (%x6);
#y6:=Do (%y6);
#x7:=Do (%x7);
#y7:=Do (%y7);
#x8:=Do (%x8);
#y8:=Do (%y8);
#x9:=Do (%x9);
#y9:=Do (%y9);
#x10:=Do (%x10);
#y10:=Do (%y10);




vx2:=[x1,x2];
vy2:=[y1,y2];

vx3:=[x1,x2,x3];
vy3:=[y1,y2,y3];

vx4:=[x1,x2,x3,x4];
vy4:=[y1,y2,y3,y4];

vx5:=[x1,x2,x3,x4,x5];
vy5:=[y1,y2,y3,y4,y5];



if a=2 then F2:=y=LinearFit([1, x], vx2, vy2, x);
end if:

if a=3 then F3:=evalf[2](LinearFit([1, x], vx3, vy3, x));
end if:


if a=4 then F4:=LinearFit([1, x], vx4, vy4, x);
end if:


if a=5 then F5:=LinearFit([1, x], vx5, vy5, x);
end if:

I was browsing on maple and i sow this:

I would use a table to insert coordinates of point like this image, but i don't know how can I do.

Can you help me plese?

Thanks in advance
