CSV Table-izer

Function Kata “CSV Table-izer”

Write a function to create a table from CSV data.

IEnumerable ToTable(IEnumerable CSV_lines)

The input to the function is a list of strings. Each string is formatted as a CSV record. Here’s an example for a possible input:

Peter Pan;Am Hang 5;12345 Einsam;42
Maria Schmitz;Kölner Straße 45;50123 Köln;43
Paul Meier;Münchener Weg 1;87654 München;65

In the input a semicolon separates values within a line. More complicated features of CSV (e.g. delimiters within a value) need not be implemented. The input always is correctly formatted; no validation necessary.

The output should be the data formatted as an “ASCII table”. The first record is interpreted as a header line. A separator line should follow the header line. The column width follows the longest value in a column (which includes the header). Here’s an example output for the above input:

Name         |Street          |City         |Age|
Peter Pan    |Am Hang 5       |12345 Einsam |42 |
Maria Schmitz|Kölner Straße 45|50123 Köln   |43 |
Paul Meier   |Münchener Weg 1 |87654 München|65 |
