MATLAB: Saving Table to a png File

imagesavetable

How would you go about saving a table to a .png file format (or any other image format, for that matter)?

Thank you!

I would store the data in a uitable and capture the image of that, or I would represent it using HTML and render that and capture the image of the result. In some cases I would use TeX or LaTeX to generate the layout.

Remember, data tables are abstract binary entities, whereas for PNG or other image formats you need to have decided upon font, and spacing, and number of digits, and shading, and rules (vertical and horizontal lines), and headers, and justification of columns, and colors, and whether you want to do subscripting and superscripting, and maybe even hypthenation strategies (if a field contains a string that need to be wrapped into multiple lines.) It gets so complicated that the rules for CSS (Cascading Style Sheets) need 6 international standards to cover all of the possibilities, but only one international standard for HTML itself.

Hello Tong,

You can create an empty DOM Table and then create DOM TableRows and DOM TableEntries. Append the TableEntries to the TableRows and then the TableRows to the Table. For the first TableEntry alone set the RowSpan value. The documentation link for TableRows and TableEntries can be found below:

https://www.mathworks.com/help/rptgen/ug/mlreportgen.dom.tablerow-class.html https://www.mathworks.com/help/rptgen/ug/mlreportgen.dom.tableentry-class.html

Also below is the sample code snippet to do create Table like the above one

import mlreportgen.dom.*
d = Document('sample', 'html-file');
i = Image(which('peppers.png'));
t = Table();
t.Border = 'Solid';
t.RowSep = 'Solid';
t.ColSep = 'Solid';
% Create First Table Row
tr = TableRow();
te = TableEntry();
% Setting the RowSpan for the first TableEntry to 3
te.RowSpan = 3;
append(te,i);
append(tr,te);
te = TableEntry();
append(te,'Text');
append(tr,te);
te = TableEntry();
append(te,'Text');
append(tr,te);
append(t,tr);
% Create Second Table Row
tr = TableRow();
te = TableEntry();
append(te,'Text');
append(tr,te);
te = TableEntry();
append(te,'Text');
append(tr,te);
append(t,tr);
% Create Third Table Row
tr = TableRow();
te = TableEntry();
append(te,'Text');
append(tr,te);
te = TableEntry();
append(te,'Text');
append(tr,te);
append(t,tr);
append(d,t);
close(d);
rptview(d);
