how to split a table to multiple table?

For example, I have the next table with dimension 16x4:

CT  = [
               196	146	154	244; 
		317	129	140	224;
		246	256	314	161;
		333	292	245	183;
                296	246	222	293;
		291	138	174	174;
		229	227	164	166;
		176	115	184	237;
		305	316	128	158;
		234	345	211	142;
		313	330	135	315;
		262	208	286	172;
                305	316	128	158;
		196	146	154	244;
		313	330	135	315;
		296	246	222	293
        ];

And I want to split it in subtables each one with a dimension of 4x4. How can i do it?

In MATLAB that is an array or a matrix, not a table...just for nomenclature.

>> CT=reshape(CT,4,4,[])
CT(:,:,1) =
   196   296   305   305
   317   291   234   196
   246   229   313   313
   333   176   262   296
CT(:,:,2) =
   146   246   316   316
   129   138   345   146
   256   227   330   330
   292   115   208   246
CT(:,:,3) =
   154   222   128   128
   140   174   211   154
   314   164   135   135
   245   184   286   222
CT(:,:,4) =
   244   293   158   158
   224   174   142   244
   161   166   315   315
   183   237   172   293
>> 

Address each 4x4 slice as

X=CT(:,:,i);

for i=1,2,3,4

Alternatively, you could just increment rows by indexing as

>> for i=1:4:size(CT,1)
CT(i:i+3,:), end
ans =
   196   146   154   244
   317   129   140   224
   246   256   314   161
   333   292   245   183
ans =
   296   246   222   293
   291   138   174   174
   229   227   164   166
   176   115   184   237
ans =
   305   316   128   158
   234   345   211   142
   313   330   135   315
   262   208   286   172
ans =
   305   316   128   158
   196   146   154   244
   313   330   135   315
   296   246   222   293

@dpb Thank you for your answer! the command "reshape" worked very well but I have another problem with this command. The problem is the order that the matrix have, please check this link:

https://la.mathworks.com/matlabcentral/answers/793307-how-to-create-a-matrix-with-all-possibles-cambinations-between-nodes-of-3-sets?s_tid=srchtitle

I did another question about this problem and i gave a test data and the codes that i am using, if you run it in matlab you can notice that the order in the values in the new matrix is different to the old matrix but i want that the both has the same order.

you can use this way to split CT,

CT  = [
               196	146	154	244; 
		317	129	140	224;
		246	256	314	161;
		333	292	245	183;
                296	246	222	293;
		291	138	174	174;
		229	227	164	166;
		176	115	184	237;
		305	316	128	158;
		234	345	211	142;
		313	330	135	315;
		262	208	286	172;
                305	316	128	158;
		196	146	154	244;
		313	330	135	315;
		296	246	222	293
        ]
     a=size(CT);
     r=1;
     n=1;
   while n<(1+a(2))
         k(:,:,n)=CT(r:a(2)*n,1:a(2))
   r=r+4;
   n=n+1;
   end
