High level representation of a Excel worksheet.

Sheets are the central structures within a workbook, and are where a user does most of his spreadsheet work. The most common type of sheet is the worksheet, which is represented as a grid of cells. Worksheet cells can contain text, numbers, dates, and formulas. Cells can also be formatted.

    `columnIndex` - - the column to set (0-based)
  Returns:
    hidden - `false` if the column is visible

### setRightToLeft

    void setRightToLeft(boolean value)

  Sets whether the worksheet is displayed from right to left instead of from left to right.

  Parameters:
    `value` - true for right to left, false otherwise.

### isRightToLeft

    boolean isRightToLeft()

  Whether the text is displayed in right-to-left mode in the window

  Returns:
    whether the text is displayed in right-to-left mode in the window

### setColumnWidth

    void setColumnWidth(int columnIndex,
                        int width)

  Set the width (in units of 1/256th of a character width)

  The maximum column width for an individual cell is 255 characters. This value represents the number of characters that can be displayed in a cell that is formatted with the standard font (first font in the workbook).

  Character width is defined as the maximum digit width of the numbers `0, 1, 2, ... 9` as rendered using the default font (first font in the workbook).
  Unless you are using a very special font, the default character is '0' (zero), this is true for Arial (default font font in HSSF) and Calibri (default font in XSSF)

  Please note, that the width set by this method includes 4 pixels of margin padding (two on each side), plus 1 pixel padding for the gridlines (Section 3.3.1.12 of the OOXML spec). This results is a slightly less value of visible characters than passed to this method (approx. 1/2 of a character).

  To compute the actual number of visible characters, Excel uses the following formula (Section 3.3.1.12 of the OOXML spec):

  `width = Truncate([{Number of Visible Characters} * {Maximum Digit Width} + {5 pixel padding}]/{Maximum Digit Width}*256)/256`

  Using the Calibri font as an example, the maximum digit width of 11 point font size is 7 pixels (at 96 dpi). If you set a column width to be eight characters wide, e.g. `setColumnWidth(columnIndex, 8*256)`, then the actual value of visible characters (the value shown in Excel) is derived from the following equation: `Truncate([numChars*7+5]/7*256)/256 = 8;` which gives `7.29`.

  Parameters:
    `columnIndex` - - the column to set (0-based)
    `width` - - the width in units of 1/256th of a character width
  Throws:
    `java.lang.IllegalArgumentException` - if width > 255*256 (the maximum column width in Excel is 255 characters)

### getColumnWidth

    int getColumnWidth(int columnIndex)

    `columnIndex` - - the column to set (0-based)
