      public ColumnSetup(Table table)
      Main Constructor.
      Parameters:
      table - the table to construct this column setup for

  • Method Details

    • prepareColumns

      private void prepareColumns()

    • getColumn

      public TableColumn getColumn(int index)
      Returns a column. If the index of the column is bigger than the number of explicitly defined columns the last column is returned.
      Parameters:
      index - index of the column (1 is the first column)
      Returns:
      the requested column

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • getColumnCount

      public int getColumnCount()
      Returns:
      the number of columns in the setup.

    • iterator

      public Iterator iterator()
      Returns:
      an Iterator over all columns

    • initializeColumnWidths

      private void initializeColumnWidths()
      Initializes the column's widths

    • computeTableUnit

      protected double computeTableUnit(TableLayoutManager tlm)
      Works out the base unit for resolving proportional-column-width() [p-c-w(x) = x * base_unit_ipd]
      Parameters:
      tlm - the TableLayoutManager
      Returns:
      the computed base unit (in millipoint)

    • computeTableUnit

      public float computeTableUnit(PercentBaseContext percentBaseContext, int contentAreaIPD)
      Works out the base unit for resolving proportional-column-width() [p-c-w(x) = x * base_unit_ipd]
      Parameters:
      percentBaseContext - the percent base context for relative values
      contentAreaIPD - the IPD of the available content area
      Returns:
      the computed base unit (in millipoints)

    • getXOffset

      public int getXOffset(int col, int nrColSpan, PercentBaseContext context)
      Determine the X offset of the indicated column, where this offset denotes the left edge of the column irrespective of writing mode. If writing mode's column progression direction is right-to-left, then the first column is the right-most column and the last column is the left-most column; otherwise, the first column is the left-most column.
      Parameters:
      col - column index (1 is first column)
      nrColSpan - number columns spanned (for calculating offset in rtl mode)
      context - the context for percentage based calculations
      Returns:
      the X offset of the requested column

    • getXOffsetRTL

      private int getXOffsetRTL(int col, int nrColSpan, PercentBaseContext context)

    • getXOffsetLTR

      private int getXOffsetLTR(int col, PercentBaseContext context)

    • getSumOfColumnWidths

      public int getSumOfColumnWidths(PercentBaseContext context)
      Calculates the sum of all column widths.
      Parameters:
      context - the context for percentage based calculations
      Returns:
      the requested sum in millipoints
