Is there any more efficient way to split a table than this

I am trying to split the table datatable into 3 smaller tables t1, t2 and t3, based on the value of the variable 'solar' in 'datatable'. accoding to three ranges:
(60-120) , (121-170) , (171<).
I did the following and its working fine but the issue is its slow and inifecient so How can I modify it to make it faster?
for ii=1:size(datatable)
if(datatable.solarT(ii)>=60 && datatable.solarT(ii)<=120)
t1(ii,:)=datatable(ii,:);
t11 = rmmissing(t1);
elseif(datatable.solarT(ii)>=121 && datatable.solarT(ii)<=170)
t2(ii,:)=datatable(ii,:);
t22 = rmmissing(t2);
else
t3(ii,:)=datatable(ii,:);
t33 = rmmissing(t3);
end
end
thank you in advance,

% Set random seed for reproducibility
rng default
% Make up a table with pretend data
N = 30;
x = rand(N,1);
solar = 200*rand(N,1);
dataTable = table(x,solar);
% Define t1 based on restricted range of table value
t1 = dataTable((dataTable.solar>=60)&(dataTable.solar<=120),:)
