how to create a table with different datatypes [ex: char, string ,numbers ,image ] in a same column?

I need to create auto generated report, which includes text, numbers , and images in a coloum of the table. and then save it as pdf,
column1:
Contents=["User Name","System Name","Date and Time","Plot"]; -(all string)
column 2:
Details=[userName,systemName,dnT, Image]
userName,systemName,dnT belongs to char/string
Image- belongs to image (jpg/png)

thanks Joshi, im looking to renerate basic report with images in the column and convert it to pdf.

Did you check the link?

Also, use exportgraphics to save the uitable (which is the chilren of uifigure) as a pdf file

[Sujay Muniraju]

NO, i believe ,its to directly save plot to JPG or to PNG images etc, i will check if it can be used to create a table with multiple varity of data

[Dyuman Joshi]

What makes you think that one can not save a file to pdf format via exportgraphics?

[Sujay Muniraju]

i understand we can export via exportgraphics pdf also thanks.

Hello Sujay Muniraju

As per my understanding, you want to create a table with different data types in a single column.

In this case, as a workaround, you can use the "table" data structure in MATLAB.

Please refer the below sample code in this regard:

% Create the data for the table
Contents = ["User Name", "System Name", "Date and Time", "Plot"]
userName = 'ABCD'
systemName = 'My System'
dnT = '2021-09-30 10:30:00'
imagePath = 'C:\path\image.jpg'

% Load the image
imageData = imread(imagePath)

% Create the table
T = table(Contents', {userName; systemName; dnT; imageData}, 'VariableNames', {'Column1', 'Column2'})

% Display the table
disp(T)

In the above code, the “Contents” variable contains the string values for the first column, and the variables “userName”, “systemName”, “dnT”, and “imageData” hold the corresponding values for the second column.

Further, to save the table as a PDF, you can use the “exportgraphics” function in MATLAB. Here's an example onhow you can save the table as a PDF:

% Save the table as a CSV file
writetable(T, 'table.csv');

% Convert the CSV file to PDF using external tools or libraries
% For example, you can use MATLAB's built-in support for calling external commands:
system('libreoffice --convert-to pdf table.csv');

Make sure to replace 'path/to/image.jpg' with the actual path to your image file.

Upon using the "exportgraphics" function with the 'ContentType', 'vector' option, MATLAB will generate a high-quality vector-based PDF file that includes the table and the image.

Besides, please note that if you want to display the image directly in the MATLAB Command Window, you can use the "imshow" function. However, if you want to include the image in the table, you will need to save it separately and provide the path or image data as shown in the sample code above.
