unless all of your column values have the same number of characters,
this is not easily achieved.

you will need to somehow know the max number of characters per column
you have/want. once you know that, you can create a tool class like
this:
public class CellFormatter {
public String space(int size) {
StringBuilder spaces = new StringBuilder();
for(int i=0; i < size; i++)
spaces.append(' ');
return spaces.toString();
}
public String format(Object obj, int cellsize) {
String value = String.valueOf(obj);
if (value.length() == cellsize) {
return value;
} else if (value.length() > cellsize) {
return value.substring(0, cellsize);
} else {
return value + space(cellsize - value.length());
}
}
}
put that into your context as "cell" (you can use VelocityTools to
automate this).
and use the it something like this:
#set( $cell = 10 )
$cell.format('Item', $cell)$cell.format('Price',
$cell)$cell.format('VAT', $cell)
#foreach( $row in [0..$rowCount] )
$cell.format($items.get($row), $cell)$cell.format($prices.get($row),
$cell)$cell.format($vats.get($row), $cell)
#end
of course, i haven't tested this code, but that's the basic idea.
