- - ### Constructor Detail

    - #### ColumnSetup

          public ColumnSetup(Table table)

      Main Constructor.
      Parameters:
        `table` - the table to construct this column setup for

  - ### Method Detail

    - #### 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 java.lang.String toString()

      Overrides:
        `toString` in class `java.lang.Object`

    - #### getColumnCount

          public int getColumnCount()

      Returns:
        the number of columns in the setup.

    - #### iterator

          public java.util.Iterator iterator()

      Returns:
        an Iterator over all columns

    - #### 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

    - #### 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
