How do I turn this 4x1 table to 60x1? It says "To assign to or create a variable in a table, the number of rows must match the height of the table."

srcFile=dir('C:\Users\arimu\OneDrive\Desktop\Training BMP\*.bmp');
for n=1:length(srcFile)
    filename=strcat('C:\Users\arimu\OneDrive\Desktop\Training BMP\', srcFile(n).name);
    I=imread(filename);
    b=imresize(I,[100 100]);
    c=rgb2gray(b);
    d=imadjust(c);
    level=graythresh(d);
    e = imbinarize(d,level);
    piccomp = imcomplement(e);
    se = strel('square',4);
    f = imdilate(piccomp,se);
    g = imerode(f,se);
    h = imclearborder(g,4);
    i = imfill(h,'holes');
    s = regionprops(i,'Area')
    t(n,1)=struct2table(s)
end

You are trying to assing a table to a single element, resulting in the image. Perhaps you want to concatenate the tables on top of each other?

Try this instead.

srcFile=dir('C:\Users\arimu\OneDrive\Desktop\Training BMP\*.bmp');
% create an empty table
t=table;
for n=1:length(srcFile)
    filename=strcat('C:\Users\arimu\OneDrive\Desktop\Training BMP\', srcFile(n).name);
    I=imread(filename);
    b=imresize(I,[100 100]);
    c=rgb2gray(b);
    d=imadjust(c);
    level=graythresh(d);
    e = imbinarize(d,level);
    piccomp = imcomplement(e);
    se = strel('square',4);
    f = imdilate(piccomp,se);
    g = imerode(f,se);
    h = imclearborder(g,4);
    i = imfill(h,'holes');
    s = regionprops(i,'Area')
    % append each table to the bottom of the existing table
    t=[t;struct2table(s)]
end
