我正在尝试编写一个函数，该函数查找字符串的最常见分隔符，它可以是逗号，空格或制表符。我的问题是该函数不读取选项卡，而是将它们读取为一堆空格。这是我的代码：

import {Commonmodule} from '@angular/common';
import {NgModule} from '@angular/core';
import {FormsModule} from '@angular/forms';
import {EffectsModule} from '@ngrx/effects';
import {StoreModule} from '@ngrx/store';
import {TranslateModule} from '@ngx-translate/core';
import {AdjustmentsStepRouteGuard} from './steps/adjustments-step/adjustments-step.guard';
import {ArchitectureStepRouteGuard} from './steps/architecture-step/architecture-step.guard';
import {ProjectNameStepRouteGuard} from './steps/project-name-step/project-name-step.guard';
import {ResultsStepRouteGuard} from './steps/results-step/results-step.guard';
import * as fromWizardStore from './store/wizard';
import * as fromTSEProjectStore from './store/TSEProject';
import {TSEProjectsEffects} from './store/TSEProject/effects/TSEProject.effects';
import {WizardStepsComponent} from './wizard-steps/wizard-steps.component';
import {WizardComponent} from './wizard.component';
import {WizardRoutingModule} from './wizard.routing.module';
import {WizardNavigationmodule} from './wizard-navigation/wizard-navigation.module';

@NgModule({
  imports: [
    Commonmodule,FormsModule,WizardRoutingModule,StoreModule.forFeature('wizard',fromWizardStore.reducer),StoreModule.forFeature('TSEProject',fromTSEProjectStore.reducer),EffectsModule.forFeature([TSEProjectsEffects]),TranslateModule,WizardNavigationmodule
  ],declarations: [WizardComponent,WizardStepsComponent],providers: [ProjectNameStepRouteGuard,ArchitectureStepRouteGuard,AdjustmentsStepRouteGuard,ResultsStepRouteGuard]
})
export class Wizardmodule {
}
