Description: These functions allow you to create simple text tables for use in textonly emails, etc. To use them simly call:
$table = text_table ($data, “-“, “|”);
$data should be a two dimensional array containing your rows and columns. Rows should be first, columns second. $data[0][3] would be row 0, column 3. The ‘-‘ and ‘|’ are the horizontal and seperating characters, respectively.
Let me know if you find this useful.
