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:
<template>
<div class="sample-tutorial">
<gc-spread-sheets class="sample-spreadsheets" @workbookInitialized="initSpread">
<gc-worksheet></gc-worksheet>
</gc-spread-sheets>
<div class="options-container">
<p>Select cell(s) that contains rule(s):</p>
<div class="option-row">
<input id="ruleCount" style="border: none;" :value="ruleCountDescription" />
</div>
<div class="option-row">
<input type="button" id="removeRule" value="Remove the selection's rule" @click="removeRule" />
<input type="button" id="clearRule" value="Remove all the rules" @click="clearRule" />
</div>
</div>
</div>
</template>
