Formula init quite slow

Hello there

A table with hundreds of rows and about twenty columns and almost 80% cells is formula, now it is quite slow to init the table, will you please give me some idea to improve it, thank you very much!

Besides, i use the option “formulas: true”, what is the difference with ruleJS.

Hi @jeffzhu4

RuleJS works with an old version of Handsontable CE and formulas as a plugin to PRO version supports the latest changes.

In February we are planning to boost the performance with the help of the layer project. It will allow us to rerender only a certain part of the table (the one we want or the one that has changed).
