Create custom table in report generator

I need to create a customized table with 3 columns and a variable number of rows. The rows must contain the data that is in an array, which I populate using a For loop. The array has 3 columns but a variable number of rows depending on the subsystem. Is there a field in Simulink Report Generator that allows me to create a table with variable rows and to insert a rule (via code) for each column?

Is it possible to use a script to create this table? If so, what is the correct format?

Hi Gugliemlo,

To create a custom table with 3 columns and a variable number of rows, you need to use the "mlreportgen.dom.Table" class correctly. The following MATLAB code demonstrates an example way to achieve this with sample data:

% Sample data array with variable number of rows and 3 columns
data = [
    1, 2, 3;
    4, 5, 6;
    7, 8, 9
];

% Create a report
import mlreportgen.report.*
import mlreportgen.dom.*

rpt = Report('MyReport', 'pdf');

% Add a title to the report
title = Paragraph('Custom Table Report');
title.Bold = true;
title.FontSize = '14pt';
add(rpt, title);

% Create a table
numRows = size(data, 1);
numCols = size(data, 2);
table = Table();

% Add header row
headerRow = TableRow();
headerContent = {'Column 1', 'Column 2', 'Column 3'};
for col = 1:numCols
    entry = TableEntry(headerContent{col});
    entry.Style = {Bold(true)};
    append(headerRow, entry);
end
append(table, headerRow);

% Populate the table with data
for row = 1:numRows
    tableRow = TableRow();
    for col = 1:numCols
        entry = TableEntry(num2str(data(row, col)));
        append(tableRow, entry);
    end
    append(table, tableRow);
end

numNewRows = 2;
numCols = size(initialData, 2);
for row = 1:numNewRows
    tableRow = TableRow();
    for col = 1:numCols
        randomValue = randi(100); % Random integer between 1 and 100
        entry = TableEntry(num2str(randomValue));
        append(tableRow, entry);
    end
    append(table, tableRow);
end

% Add table to report
add(rpt, table);

% Close and view the report
close(rpt);
rptview(rpt);
