如何使用TextEditor.setDecorations()在VSCode中动态更改栏间距图标

const vscode = require('vscode');

function activate(context) {
    let disposable = vscode.commands.registerCommand('extension.changeDecoration', function () {
        let editor = vscode.window.activeTextEditor;
        if (editor) {
            let decorationType = vscode.window.createTextEditorDecorationType({
                // 定义装饰器的样式
                borderWidth: '1px',
                borderStyle: 'solid',
                overviewRulerColor: 'blue',
                overviewRulerLane: vscode.OverviewRulerLane.Right,
                light: {
                    // 在浅色主题下的样式
                    borderColor: 'darkblue'
                },
                dark: {
                    // 在深色主题下的样式
                    borderColor: 'lightblue'
                }
            });

            let range = editor.document.validateRange(new vscode.Range(0, 0, editor.document.lineCount, 0));
            let decoration = { range };

            // 应用装饰器到文本编辑器中
            editor.setDecorations(decorationType, [decoration]);
        }
    });

    context.subscriptions.push(disposable);
}
exports.activate = activate;
