I want to convert this data into the image shown after

paths = ["path1";"path2";"path3"];
cellData = {1,2,3,4;5,6,7,8;9,10,11,12};

How do I do this?

Do all rows have the same number of columns in your cell array data ?

@Siddharth Bhutiya yes they do.

paths = ["path1";"path2";"path3"];
cellData = {1,2,3,4;5,6,7,8;9,10,11,12};
imageFilename = paths;
vehicle = cell2mat(cellData);
table(paths, vehicle)
ans = 3x2 table
     paths           vehicle      
    _______    ___________________

    "path1"    1     2     3     4
    "path2"    5     6     7     8
    "path3"    9    10    11    12

If you are going to put more than one group into the vehicle area, then instead

paths = ["path1";"path2";"path3"];
cellData = {1,2,3,4;5,6,7,8;9,10,11,12};
imageFilename = paths;
vehicle = num2cell(cell2mat(cellData),2);
table(paths, vehicle)
ans = 3x2 table
     paths       vehicle   
    _______    ____________

    "path1"    {1×4 double}
    "path2"    {1×4 double}
    "path3"    {1×4 double}

you will not be able to get the actual numbers to display in that situation

Why not just:

cell2mat(yourCellarray);

Perhaps Variable Browser shows them. The command window will not.

@Walter Roberson just checked. It does. Could you please post your comment as an answer so I can accept it? I'll edit my question with the updated images.
