Hello,
I need to append a string based on a rule. I want all of my strings to be 5 characters.
Input:
string number
aaa 3
hhh 3
abhag 5
aq 2
p 1
Output:
string
00aaa
00hhh
abhag
000aq
0000p
Is this possible?
Thanks in advance
@zielinska_km the function should be padLeft in the Column Expressions – KNIME Hub
padLeft(column("column1"),5 ,"0" )

I get error message: Compilation of script failed: Cannot invoke “javax.script.ScriptEngine.eval(String)” because “engine” is null
What should I do?
@zielinska_km check if you have installed the extension and maybe provide a sampel workflow that shows what you are doing. Also make sure you have the latest KNIME version.

Hi @zielinska_km
You can use the String Manipulation node.

I have installed the extension, but I still get the same warning.
