MATLAB: Function subsindex is not defined for values of class ‘mlreportgen.dom.Image’

2x2 tableimagesimages into tableMATLABMATLAB Report Generatorr2017breport generator toolkittable images

Not sure what this error is trying to say as I am not indexing anything. What I am trying to do is put an image into a table and then display that table. My end goal is to create a 2×2 table filled with 4 images.

The error I get is:

Function 'subsindex' is not defined for values of class 'mlreportgen.dom.Image'.
Error in sad (line 9)
entry=TableEntry(bojack)

Here is my code:

import mlreportgen.dom.*;
import mlreportgen.report.* 
rpt = Report('C:\Users\GOE7ABT\Desktop\myreport1.pdf');
bojack=Image('C:\Users\GOE7ABT\Desktop\21-bojack-12.w710.h473.jpg');
table=Table();
entry=TableEntry(bojack)
append(table,entry)
add(rpt,table)
close(rpt);
rptview(rpt.OutputPath);

You likely have a variable named TableEntry. You may have intended your command "entry=TableEntry(bojack)" to create an instance of this class, but variables are higher in the precedence order than imported package functions. Rename or remove your variable.

An Image can not be directly appended to a TableRow. I would suggest to create a TableEntry with the Image, and then append TableEntry to TableRow, followed by appending TableRow to the Table.

import mlreportgen.dom.*;
import mlreportgen.report.* 
rpt = Report('C:\Users\GOE7ABT\Desktop\myreport1.pdf');
bojack=Image('C:\Users\GOE7ABT\Desktop\21-bojack-12.w710.h473.jpg');
table=Table();
entry=TableEntry(bojack);
row1=TableRow();
append(row1,entry);
append(table,row1);
add(rpt,table)
close(rpt);
rptview(rpt.OutputPath);

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);
