I am printing multiple tables in a report but I dont know how long each table will be (and some tables are multiple pages long) and I dont want to start a new table at the bottom of a page if there is only a few rows left. I am aware that the PageBreak option exist but I also dont want to waste a whole page just if there is just one or two rows at the top of the page. Given that a page has always the same height, I figured that if I could find out how high my tables are (in pixels I suppose) then I could automatically place them as I want. In a report, how can you find out the height of table in pixels ?

Im using the report generator. For example, if we tweak the example here (https://www.mathworks.com/help/rptgen/ug/define-styles-programmatically.html) I wouldnt want another table starting right under this one in the report as there is not enough room at the bottom of the page but I also dont want to use pagebreak automatically if there is only a couple of lines at the top of the page

Hi Blue,
Mlreport.dom package has a class named RowHeight, this can be used to set and modify the height of each row in the table. Multiplying the default row height (1in) to the number of rows will give you the height of the total report.
Refer to this documentation for more information:
https://www.mathworks.com/help/rptgen/ug/mlreportgen.dom.rowheight-class.html
Hope this helps.
