How can I store vectors of different sizes into a column array to be then added to Table that was created previously?

I wrote two codes that process images. The first script loads the images, allows the user to select the points of interest then stores these in a Table. The next script takes these coordinate values and creates vectors for the region of interst highlighted for each sample. I want to store these vectors in the Table from the previous script but I am running into two issues.
The first is how do I append the table (create new column and add it to table). The second issue is that when I concatnate the vectors (of different sizes) in my loop. I am given an eorror "deimensions of arrays being concatenated are not conisistent". How would I go about resolving this? The vectors will always be of different sizes. My goal is to store these vectors with their appropirate files to be later used for calculatoins and plots ( I plan to plot all the intensity profile for the samples on one plot)/ I am including a sample of the table the first code creates below:
One of the challneges is that I want to store a vector in one cell to be accessed later for when I plot my values for each of my files.

end
ROIint=[ROIint; Intensity]
end

As suggested above, you can append variable length vectors into a cell array.
For this particular case, you can create a table with the maxium possible columns and use NaN for missing values.
