java.lang.Object

io.keikai.ui.impl.MergeMatrixHelper

All Implemented Interfaces:

Serializable

public class MergeMatrixHelper
extends Object
implements Serializable

Each sheet has its own MergeMatrixHelper and it manages merged cells. Because current implementation of spreadsheet only support horizontal merged cell, So, use this helper to help Spreadsheet control merged cell in horizontal only
