hi guys, can u tell me a different way to sort table by 2 variable columns which more simple than my method?

I want to sort jointTOS by its X and Z from minimum to maximum but X is the priority.

Here the code :

clear;

clc;

H = 5;

L = 15;

Ns = 2;

Nb = 1;

PortalHeight = H;

Bayspan = L;

NumberStory = Ns;

NumberBay = Nb;

% Variable1

h = [0.8,1.00,1.20,1.40,1.6,1.80];

% Variable2

Lss = [2.00,2.40,2.80,3.20,3.60,4.00];

% Variable3

Nss = [2,3,4];

% Definition

Var1HeightofTrussBeam = h;

Var2LengthSpecialSegment = Lss;

Var3NumberSpecialSegment = Nss;

% % Xbase = zeros(1,length(Totalvariant));

% % Zbase = zeros(1,length(Totalvariant));

% % Xcol = zeros(1,length(Totalvariant));

% % Zcol = zeros(1,length(Totalvariant));

% % Xos = zeros(1,length(Totalvariant));

% % Zos = zeros(1,length(Totalvariant));

% % Xss = zeros(1,length(Totalvariant));

% % Zss = zeros(1,length(Totalvariant));

% % X = zeros(1,length(Totalvariant));

% % Z = zeros(1,length(Totalvariant));

% % jointbase = zeros(1,length(Totalvariant));

% % jointcolumn = zeros(1,length(Totalvariant));

% % jointordinarysegment = zeros(1,length(Totalvariant));

% % jointtopordinarysegment = zeros(1,length(Totalvariant));

% % jointbottomordinarysegment = zeros(1,length(Totalvariant));

% % jointspecialsegment = zeros(1,length(Totalvariant));

% % jointtopspecialsegment = zeros(1,length(Totalvariant));

% % jointbottomspecialsegment = zeros(1,length(Totalvariant));

ijk = 0;

for i = 1:numel(h)

for j = 1:numel(Lss)

for k = 1:numel(Nss)

ijk = ijk+1;

Variantmodel{ijk,:} = table(ijk,h(i),Lss(j),Nss(k),'VariableNames',{'VariantID','Height','Length','Number'});

%% Cooridinate Point Base(base)

Xbase{ijk,:} = L*(0:NumberBay);

Zbase{ijk,:} = repelem(0,1,length(Xbase{ijk,:}));

%% Column(col)

Xcolumn = L*(0:NumberBay);

Zcolumn = repelem(H*(1:NumberStory),1,length(Xcolumn));

Xbotbeam = L*(0:NumberBay);

Zbotbeam = repelem((H*(1:NumberStory)-h(i)),1,length(Xbotbeam));

% replicate [X] to be the same size as [Z] for plotting:

Xcol{ijk,:} = repmat([Xcolumn,Xbotbeam],1,NumberStory);

Zcol{ijk,:} = [Zcolumn,Zbotbeam];

%% Cooridinate Point Ordinary Segment (os)

% calculate span length of ordinary segment

Los = (L-Lss(j))/2;

Nos = Los/h(i);

Nos = round(Nos);

los = Los/Nos;

totalspan{ijk,:} = los*Nos*2+Lss(j);

if totalspan{ijk,:} == 15.000

checkspan{ijk,:} = "correct span";

else

checkspan{ijk,:} = "span must be 15m";

end

% top and bottom joint of ordinary segment(os)

XTopOrdinarySegment = reshape([los*(1:Nos),(L/2+Lss(j)/2)+los*(0:Nos-1)].'+L*(0:(NumberBay-1)),1,[]);

XBottomOrdinarySegment = XTopOrdinarySegment;

ZTopOrdinarySegment = repelem(H*(1:NumberStory),1,2*Nos*NumberBay);

ZBottomOrdinarySegment = repelem(H*(1:NumberStory)-h(i),1,2*Nos*NumberBay);

%% Cooridinate Point Special Segment (ss)

% calculate span length of special segment

lss = Lss(j)/Nss(k);

XTopSpecialSegment = reshape((lss*(0:Nss(k))+L/2-Lss(j)/2).'+L*(0:(NumberBay-1)),1,[]);

XBottomSpecialSegment = XTopSpecialSegment;

ZTopSpecialSegment = repelem(H*(1:NumberStory),1,length(XTopSpecialSegment));

ZBottomSpecialSegment = repelem(H*(1:NumberStory)-h(i),1,length(XBottomSpecialSegment));

% replicate [X] to be the same size as [Z] for plotting:

Xss{ijk,:} = repmat([XTopSpecialSegment,XBottomSpecialSegment],1,NumberStory);

Zss{ijk,:} = [ZTopSpecialSegment,ZBottomSpecialSegment];

%% Plot Cooridinate Point (X,Z)

X{ijk,:} = [Xbase{ijk,:},Xcol{ijk,:},Xos{ijk,:},Xss{ijk,:}];

Z{ijk,:} = [Zbase{ijk,:},Zcol{ijk,:},Zos{ijk,:},Zss{ijk,:}];

scatter(X{ijk,:},Z{ijk,:},'filled'),grid on

%check angle

tangent = (Lss(j)/Nss(k))/h(i);

anglespecialsegment(ijk) = atand(tangent);

%% Name the Joint

end

% Verify Variants Which Passed the Angle Requirement

%% Name the Frame

end

end

% top ordinary segment (TOS)

end

here the resut that i want :
