Need help making the code below run in parfor loop. The errors are:

"The parfor loop cannot run due to the way symTable is used"

"The parfor loop cannot run due to the way asymTable is used"

freqVec = freqMin:freqStep:freqMax;
fullModes = 1:4;
symTab = ["Frequency" ; "S"+string(fullModes'-1) + " Cp"];
asymTab = ["Frequency" ; "A"+string(fullModes'-1) + " Cp"];
tableTypes = repmat("double",1,fullModes(end)+1);
symTable = table('Size',[length(freqMin:freqStep:freqMax) fullModes(end)+1],'VariableNames', ...
    symTab,'VariableTypes',tableTypes);
asymTable = table('Size',[length(freqMin:freqStep:freqMax) fullModes(end)+1],'VariableNames', ...
    asymTab,'VariableTypes',tableTypes);
parfor ii = 1:length(freqVec)
    currentFreq = freqVec(ii);
    
    symCTR = 1;
    asymCTR = 1;
    
    %LOTS OF CODE HERE TO DETERMINE Cp, which is a 2x10 matrix
    for modeType = 1:2
        if any(CpFin(1,:) ~= 0,2) % store root results into table based on mode.
            symTable(ii,1) = {currentFreq};
            asymTable(ii,1) = {currentFreq};
            for j = 1:size(CpFin,2)
                if modeType == 1
                    if symCTR > width(symTable)-1
                        continue
                    elseif CpFin(1,j) == 0
                        continue
                    elseif round(CpFin(1,j)) == Cs || round(CpFin(1,j)) == Cl
                        continue
                    end
                    symTable(ii,symCTR+1) = {CpFin(1,j)};
                    symCTR = symCTR + 1;
                else
                    if asymCTR > width(asymTable)-1
                        continue
                    elseif CpFin(1,j) == 0
                        continue
                    elseif round(CpFin(1,j)) == Cs || round(CpFin(1,j)) == Cl
                        continue
                    end
                    asymTable(ii,asymCTR+1) = {CpFin(1,j)};
                    asymCTR = asymCTR + 1;
                end
            end
        end
