Enum HorizontalAlignment

An enumeration of the supported horizontal alignment types.

To call an enum, you call its parent class, name, and property. For example, DocumentApp.HorizontalAlignment.LEFT.

Use the HorizontalAlignment enumeration to manipulate the alignment of Paragraph contents.

const body =
    DocumentApp.getActiveDocument().getActiveTab().asDocumentTab().getBody();

// Insert a paragraph and a table at the start of the tab.
const par1 = body.insertParagraph(0, 'Center');
const table = body.insertTable(1, [['Left', 'Right']]);
const par2 = table.getCell(0, 0).getChild(0).asParagraph();
const par3 = table.getCell(0, 0).getChild(0).asParagraph();

// Center align the first paragraph.
par1.setAlignment(DocumentApp.HorizontalAlignment.CENTER);

// Left align the first cell.
par2.setAlignment(DocumentApp.HorizontalAlignment.LEFT);

// Right align the second cell.
par3.setAlignment(DocumentApp.HorizontalAlignment.RIGHT);
