[沟通中] 【v16】如何使用代码去除筛选中的某一个条件？

使用以下代码进行筛选

var condition1 = new GC.Spread.Sheets.ConditionalFormatting.Condition(GC.Spread.Sheets.ConditionalFormatting.ConditionType.textCondition, {
              compareType: GC.Spread.Sheets.ConditionalFormatting.GeneralComparisonOperators.equalsTo,
              expected: '社区1'});

var condition2 = new GC.Spread.Sheets.ConditionalFormatting.Condition(GC.Spread.Sheets.ConditionalFormatting.ConditionType.textCondition, {
              compareType: GC.Spread.Sheets.ConditionalFormatting.GeneralComparisonOperators.equalsTo,
              expected: '社区2'});

...

var conditionn = new GC.Spread.Sheets.ConditionalFormatting.Condition(GC.Spread.Sheets.ConditionalFormatting.ConditionType.textCondition, {
              compareType: GC.Spread.Sheets.ConditionalFormatting.GeneralComparisonOperators.equalsTo,
              expected: '社区n'});

filter.addFilterItem(col, condition1);
filter.addFilterItem(col, condition2);
...
filter.addFilterItem(col, conditionn);

filter.filter()

如何单独去除社区n这一项的筛选条件，重新进行筛选？
