L =[1 2 0.1 0.2 0.02
    1 4 0.05 0.2 0.02
    1 5 0.08 0.3 0.03
    2 3 0.05 0.25 0.03
    2 4 0.05 0.1 0.01
    2 5 0.1 0.3 0.02
    2 6 0.07 0.2 0.025
    3 5 0.12 0.26 0.025
    3 6 0.02 0.1 0.01
    4 5 0.2 0.4 0.04
    5 6 0.1 0.3 0.03]
ln = L(:,1);
rn = L(:,2);
Pt=[ 25.33, 41.57, 33.1, 1.854, 32.48, 16.22, 24.78, 16.93, 44.92, 4.045, 0.2999]
Pt = 1×11
   25.3300   41.5700   33.1000    1.8540   32.4800   16.2200   24.7800   16.9300   44.9200    4.0450    0.2999

so i want to use table(if there is any other way thatn using table please tell me) and i want 3 column (FromBus,ToBus,P)

P is my Pt

FromBus is ln

ToBus is rn

it should be like this

FromBus ToBus P
2 25.33
4 41.57
5 33.1
3 1.854 
4 32.48 
5 16.22
6 24.78
5 16.93
6 44.92 
5 4.045
6 0.2999

在 MATLAB Online 中打开

T = table(ln,rn,Pt,'VariableNames',{'From Bus','To Bus','P',});

i dont know if im doing it right

Error using matlab.internal.tableUtils.makeValidName (line 39)

'From Bus' is not a valid variable name.

Error in matlab.internal.table.tableVarNamesDim (line 37)

matlab.internal.tableUtils.makeValidName(labels,'varnamesError');

Error in table (line 256)

t.varDim = matlab.internal.table.tableVarNamesDim(numVars,varnames); % error if invalid,

duplicate, or empty

Error in DCPowerFlow (line 92)

T = table([ln,rn,Pt],'VariableNames',{'From Bus','To Bus','P',});

Prior to release R2019b table variable names were required to be valid MATLAB identifiers. Release R2019b relaxes this restriction, allowing the use of spaces (among other symbols.)

#Check Pt array size? Use ; for column vector or use traspose in the table data.

T=table(ln,rn,Pt','VariableNames',{'From Bus','To Bus','P',})

You may need to convert the symbolic values to double?

Try

T=table(ln,rn,double(Pt)','VariableNames',{'From Bus','To Bus','P',})
