TableBuilder

27 dic 2022

TableBuilder is a library designed to make it easier to create tables in PineScript.
It allows you to more flexibly define the structure of a table before actually building it.

Features:

• Style inheritance: styles are inherited from Table, to Column, to Row, and then Cell.
  
• Columns are useful for propagating/reusing style but they are not required.
  
• Add rows with different numbers of cells. The resultant number of columns in the table will be determined by the max number of cells vs the number of defined columns.
  
• Auto text color: Instead of having to set the font color for every cell, the color is automatically determined by the luminosity of the background color.
  

See the 'Demo' section of the code for an example.
