-----------------------------------

Hi [~jdenise] I did not try with '-l', I can look into this in CLI tomorrow. 
I'm not sure I follow "constraint the with of a column in SimpleTable to be of length 0", Do you mean to change in [SimpleTable.java#L82|https://github.com/wildfly/wildfly-core/blob/5ff6433a5f06051ce8c29c654e9957d463e9ce77/cli/src/main/java/org/jboss/as/cli/util/SimpleTable.java#L82] something like 

{code:java}
if(columnLengths[i] < value.length() + 1 && value.length() < terminalWidth) {
    columnLengths[i] = value.length() + 1;
}
{code}

to make output like 2nd screenshot ?

> When 'ls' operation is performed over 'provider-loader' element, the output is very ugly - I get many empty lines with one very long attribute value and few more attributes with simple values.
> Expected: no empty lines between printed attributes so the output does not take like 4 screen size.
