仅在一种情况下无法实现水平对齐

Question

我设置了这些样式：

var titleStyle = {};
titleStyle[DocumentApp.Attribute.FONT_FAMILY] = 'Calibri';
titleStyle[DocumentApp.Attribute.FONT_SIZE] = 20;
titleStyle[DocumentApp.Attribute.BOLD] = true;
titleStyle[DocumentApp.Attribute.UNDERLINE] = true;
titleStyle[DocumentApp.Attribute.HORIZONTAL_ALIGNMENT] = DocumentApp.HorizontalAlignment.CENTER;

var sectionStyle = {};
sectionStyle[DocumentApp.Attribute.FONT_FAMILY] = 'Calibri';
sectionStyle[DocumentApp.Attribute.FONT_SIZE] = 18;
sectionStyle[DocumentApp.Attribute.BOLD] = true;
sectionStyle[DocumentApp.Attribute.UNDERLINE] = true;
sectionStyle[DocumentApp.Attribute.HORIZONTAL_ALIGNMENT] = DocumentApp.HorizontalAlignment.CENTER;

这使标题居中：

var docTitle = noteBody.appendParagraph(title);
docTitle.setAttributes(titleStyle);

这不会使节标题居中！

var nextHeader = noteBody.appendTable(headerTable);
nextHeader.setAttributes(sectionStyle);

但它确实可以做所有其他事情 - 大小、粗体、下划线等。只是不居中！我可能会错过什么？完整脚本如下

  var date = new Date();
    var zone = Session.getScriptTimeZone();
    var formattedDate = Utilities.formatDate(date, zone, 'MM/dd/yy hh:mm a');
  var docName = "title here - " + formattedDate;
  var doc = DocumentApp.create(docName);
  var docFiles = DriveApp.getFilesByName(docName);
  var docFile = docFiles.next();
  var noteBody = doc.getBody();
  var document = [];

Answer 1

从您的显示脚本中，我可以注意到您的实际问题与表格单元格相关。来自

The line where I try to setAttributes is marked off with ////HERE.

，既然如此，下面的修改如何？如果是单元格值，则使用段落。

请按如下方式修改您的显示脚本。

来自：

var headerTable = [];
headerTable.push([items[i].getTitle()]);

var nextHeader = noteBody.appendTable(headerTable);
nextHeader.setAttributes(sectionStyle);

致：

var headerTable = [];
headerTable.push([items[i].getTitle()]);

var nextHeader = noteBody.appendTable(headerTable);

// Added
nextHeader.getCell(0, 0).getChild(0).asParagraph().setAlignment(DocumentApp.HorizontalAlignment.CENTER);

nextHeader.setAttributes(sectionStyle);

• 通过此修改，

  items[i].getTitle()

  的单元格值的对齐设置为中心。

注：

• 在此示例中，假设您的显示脚本工作正常。请注意这一点。

不幸的是，我不知道你的实际情况。所以，我无法测试你的整个脚本。但是，当我使用您的显示脚本测试一个简单的示例脚本时，我确认修改后的脚本有效。以下脚本是用于测试的简单示例脚本。运行此脚本时，会创建一个新的 Google 文档。打开后可以看到“样本值”的文字居中对齐。

function sample() {
  const noteBody = DocumentApp.create("sample").getBody();


  // This is from your showing script.
  var sectionStyle = {};
  sectionStyle[DocumentApp.Attribute.FONT_FAMILY] = 'Calibri';
  sectionStyle[DocumentApp.Attribute.FONT_SIZE] = 18;
  sectionStyle[DocumentApp.Attribute.BOLD] = true;
  sectionStyle[DocumentApp.Attribute.UNDERLINE] = true;
  sectionStyle[DocumentApp.Attribute.HORIZONTAL_ALIGNMENT] = DocumentApp.HorizontalAlignment.CENTER;

  // This is from your showing script.
  var tableStyle = {};
  tableStyle[DocumentApp.Attribute.FONT_SIZE] = 12;
  tableStyle[DocumentApp.Attribute.BOLD] = false;
  tableStyle[DocumentApp.Attribute.UNDERLINE] = false;

  // Below script is from your showing script.
  var headerTable = [];
  headerTable.push(["sample value"]); // This is a sample value.
  var nextHeader = noteBody.appendTable(headerTable);
  nextHeader.getCell(0, 0).getChild(0).asParagraph().setAlignment(DocumentApp.HorizontalAlignment.CENTER);
  nextHeader.setAttributes(sectionStyle);
  nextHeader.setAttributes(sectionStyle);
  nextHeader.setBorderWidth(0);
}
