PadStart / String Layer

Add padding characters to the left side of strings until they reach a specified length. Similar to Python's str.rjust() or Rust's pad_to_width_with_alignment(). Useful for:

Right-aligning text
Zero-padding numbers (e.g., 42 -> 0042)
Creating fixed-width codes
Formatting identifiers

Table

Select

column

The string column to pad. Strings longer than Length remain unchanged.

Length

u32

Target length (Length) for padded strings. Examples:

abc with length=5 becomes ⎵⎵abc
42 with length=4 and fill_char=0 becomes 0042
long_text with length=4 stays long_text

FillChar

string

Single character (FillChar) for padding. Common uses:

Space ( ) for right alignment
Zero (0) for numeric padding
Hash (#) for reference numbers

Name for the new column. If not provided, the system generates a unique name. If AsColumn matches an existing column, the existing column is replaced. The name should follow valid column naming conventions.
