occaisonally InfoPath has to be beaten into submission. depending what i am working on and the last time I rebooted I can receive a multitude or issues. Still all in all you can find a better product without developing it. It may not be fun or easy, but IP allows to click a field. this displays about 8 square dots, that allow for resizing/ select the dots on the right and shrinkl your field. this shouyld change the % to px. if this all fails, split the cells to the size you need, then hide the borders. nothing like a table to organize your data.
