Hi @wuzunqian

Please check this short tutorial about performance in Handsontable: https://docs.handsontable.com/pro/1.10.0/tutorial-performance-tips.html

if you set width and height for Handsontable and its elements the script doesn’t need to recalculate the table dimensions while user performs actions.
