How do I control number formatting for 'mlreportgen.ppt.Table' object?

I want to control number formatting in a 'mlreportgen.ppt.Table' object. If I have a ‘mlreportgen.dom.NumberFormat’ object, I can specify the numbers in the table to have a chosen precision using 'NumberFormat' or 'setDefaultNumberFormat', but I cannot find any way to do this for 'mlreportgen.ppt.Table' object. 

I'd like to use general formatting strings like '%1.2f' or a precision spec from the 'round' function. My source data is in tabular form. How do I accomplish this workflow?

For ‘mlreportgen.ppt.Table’ objects, one possible way to set number format is to use 'compose' function to format data into multiple strings. Since your source data is in tabular format, you could first use 'table2array' function to convert the tabular data to an array and then use the 'compose' function to convert data to desired number format.

An example is given below:

T = table([1;2;3],[2; 4; 6 ],[3 ; 6 ; 9 ],... 

    'VariableNames',["One" "Two" "Three"]); % create a table

ArrayTable = table2array(T); % convert tabular data to an array

formatSpec = '%.2f'; % desired number format

StrNum = compose(formatSpec,ArrayTable); % convert data to desired number format

StrTable = [T.Properties.VariableNames; StrNum];  % Obtain the original column header

FormattedTable = table(StrTable); % convert back to table
