# Table Calculations Prerequisites

  

🕐 _1 min read_

This section assumes a basic understanding of table calculations, including addressing and partitioning. For more information, see the following documentation topics:

- [Transform Values with Table Calculations](https://help.tableau.com/current/pro/desktop/en-us/calculations_tablecalculations.htm)
- [Quick Table Calculations](https://help.tableau.com/current/pro/desktop/en-us/calculations_tablecalculations_quick.htm)
- [Customize Table Calculations](https://help.tableau.com/current/pro/desktop/en-us/calculations_tablecalculations_custom.htm)

Quick table calculations are a nice interface that matches the _Quick Table Calculation_ dialog in Tableau. However, anything you can do with quick table calculations, you can also do with [custom table calculations](https://help.tableau.com/v0.0/api/vizql-data-service/en-us/docs/vds_table_calcs_custom.html). Custom table calculations are the equivalent of typing in a calculation.
