This appears to be a bug with either the Layout Tool or the Render Tool. When I setup two Tables using the Horizontal Layout Tool and export to Excel using the Render tool, the font size of the bottom-right cell of the first table is too large. No amount of changing the font properties within the Alteryx Reporting tools appears to fix this.
