Method Summary

Modifier and Type	Method and Description
static ILogicalTable	logicalTable(IGridTable table) If there is no merged cells in the top row and left column - returns SimpleLogicalTable in other case return LogicalTable

Method Detail

logicalTable

public static ILogicalTable logicalTable(IGridTable table,
                                         ILogicalTable columnOffsetsTable,
                                         ILogicalTable rowOffsetsTable)

logicalTable

public static ILogicalTable logicalTable(IGridTable table)

If there is no merged cells in the top row and left column - returns SimpleLogicalTable in other case return LogicalTable

Parameters:

table - Original source grid table.

Returns:

ILogicalTable table with correctly calculated height and width.

mergeBounds

public static ILogicalTable mergeBounds(ILogicalTable leftRows,
                                        ILogicalTable topColumns)

This method will produce a logical table defined by 2 tables: leftRows and topColumns Both tables are logical tables. Rows in a new table will be defined by rows in leftRows table, and columns by the columns topColumns table. "Left" and "top" points to relative location of defining tables. It should be used only with "normal" orientation

Parameters:

leftRows -

topColumns -

Returns:

make1ColumnTable

public static ILogicalTable make1ColumnTable(ILogicalTable t)

Returns:

table with 1 column, if necessary transposed, caller is responsible to check that table is either 1xN or Nx1

unmergeColumns

public static ILogicalTable unmergeColumns(ILogicalTable table,
                                           int fromColumn,
                                           int toColumn)
