hi
spaces are not significant in listview
also I put an "a" and the numbers are aligned
then I replaced the a with space and the numbers are no longer aligned
there wouldn't be an invisible character that would align my numbers in my listview?
regards
Try
\t
or
 
unfortunately neither one nor the other
It would really help if you provided a screenshot of your relevant blocks as well as a screenshot of how the listview looks like, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

hi
what i want is to get an alignment like this in a listview without the a
aaaaa19788
aaaaaaa333
aaaa105555
I used a's to make the format and then replaced the a's with space but it didn't work the numbers were no longer aligned
if I could have made them transparent ....
hi
I know but it doesn't make it easy to read
regards
Another way is to put the numbers into a right aligned label, but then you lose the selectability....
Put them in an HTML table that consists of a single column, right aligned.
Of course!
Here is an example using a google sheet to hold the list of numbers, and a url you can call to do just this:
https://docs.google.com/spreadsheets/d/1zz2oqSMKlAb7DpRzE6WamaEHHQcEg5jTp6NmfgmEer8/gviz/tq?tqx=out:html
again, not selectable, but additional html and webviewstring could make that so.
A further issue there is the font - it may or may not support the more "exoctic" hidden characters that UTF-8 has to offer, but you can try them:
U+0009 character tabulation
U+000A line feed
U+000B line tabulation
U+000C form feed
U+000D carriage return
U+0020 space
U+0085 next line
U+00A0 no-break space
U+1680 ogham space mark
U+180E mongolian vowel separator
U+2000 en quad
U+2001 em quad
U+2002 en space
U+2003 em space
U+2004 three-per-em space
U+2005 four-per-em space
U+2006 six-per-em space
U+2007 figure space
U+2008 punctuation space
U+2009 thin space
U+200A hair space
U+200B zero width space
U+200C zero width non-joiner
U+200D zero width joiner
U+2028 line separator
U+2029 paragraph separator
U+202F narrow no-break space
U+205F medium mathematical space
U+2060 word joiner
U+3000 ideographic space
U+FEFF zero width non-breaking space
.....Well, tried them myself 
The issue with prefixing any space is that a monospace font is needed for accuracy, but ListView does not offer a font typeface option. So, the best solution is an HTML table - unless the enhanced ListViews available as an extension can do better:
https://puravidaapps.com/extensions.php
If you want an extension-free work around,
use a stack of buttons and a Canvas scroll bar to drag your list of Element values across
the little window of button Texts ...
In this case, pick a monospace font for the buttons, and set them right aligned.
I had the same problem and solved it by calculating character width, decimal width, and padded witdth at app startup, then setting each listview width to the maximum calculated width.
I created a listview inside a horizontal scrolling arrangement with both having automatic width and height.
I then add the following single elements to the listview using a 100ms timer and capture the width of the listview after each element is inserted.
The decimal point width is the width of 2) minus 1).
The padded width is the wdith of 3) minus the decimal point width.
The character width is the width of 1) minus the padded width.
This works very well for me and I hope this helps.
