使用 Specific Text 规则

var style = new GC.Spread.Sheets.Style();
style.backColor = "red";
var ranges=[new GC.Spread.Sheets.Range(0,0,10,1)];
activeSheet.conditionalFormats.addSpecificTextRule(GC.Spread.Sheets.ConditionalFormatting.TextComparisonOperators.Contains, "test", style, ranges);
activeSheet.setValue(0, 0, "testing");
activeSheet.setValue(1, 0, "test");
activeSheet.setValue(2, 0, "a");
activeSheet.setValue(3, 0, "t");
