To add conditional formatting in SpreadJS, first use the conditionalFormats method to get the conditional format for the sheet. Then you can create a conditional rule and use the addRule method to add it. Also you can use the specified rule's add method, like addSpecificTextRule, addCellValueRule, and so on. For example:
After you add rules to the sheet, you can use the getRule method to return the rule using the rule index or get all the conditional rules. For example:
If you want to remove the conditional rule, use the removeRule, removeRuleByRange, or clearRule methods. For example:
