Methods

Visualize()

• Signature: public function Visualize($table_data,$font_size)
• Parameters:
  • $table_data
  • $font_size

__construct()

Construct a text table object @param numeric $max_width -- the maximum width of the table

• Signature: public function __construct($max_table_width,$font_metric,$hyphen,$encoding,$col_spacing,$widthstyle,$algorithm)
• Parameters:
  • $max_table_width
  • I2CE_FontMetric $font_metric
  • I2CE_Hyphen $hyphen
    default is null
    • Default Value: null
  • &$encoding
  • numeric $col_spacing
    the spacing used between the columns. Default to 0
    • Default Value: 0
  • string $widthstyle
    how we determine the width of the columns. Defaults to 'Header'
    • Default Value: 'Header'
  • int $algorithm
    the word wrapping algorithm: default = 'Greedy' @param I2CE_Encoding encoding -- the encoding we want to use
    • Default Value: 'Greedy'

adjustDesiredWidths()

helper function to adjust the desired width of a column to those allowable by the maxium size

• Signature: protected function adjustDesiredWidths($desired_widths,$width)
• Parameters:
  • $desired_widths
  • $width

getColSpacing()

• Signature: public function getColSpacing()

getFontMetric()

• Signature: public function getFontMetric()

getWidths()

Get the currently set width of the columns. If we are using one of the algorithms to determine the widths, it will be set to the widths used in the generation of the last text table

• Signature: public function getWidths()
• Returns: array
  of numeric

getWidthsFromAllCells()

• Signature: protected function getWidthsFromAllCells($table_data,$font_sizes)
• Parameters:
  • $table_data
  • $font_sizes

getWidthsFromHeader()

• Signature: protected function getWidthsFromHeader($row_data,$font_sizes)
• Parameters:
  • $row_data
  • $font_sizes

setColSpacing()

• Signature: public function setColSpacing($col_spacing)
• Parameters:
  • $col_spacing

setFontMetric()

• Signature: public function setFontMetric($fm)
• Parameters:
  • $fm

setMaxTableWidth()

• Signature: public function setMaxTableWidth($table_width)
• Parameters:
  • $table_width

setMinCellWidth()

• Signature: public function setMinCellWidth($width)
• Parameters:
  • $width
    • Default Value: 0

setWidthStyle()

Set the table's column widths @param sting $widthsstyle. Possible values are 'Explicit' the user sets the widths via setWidths(). 'Header' --n we try to guess good widths by looking at the first row of the table. 'All' then we try to guess good widths by examining all rows.

• Signature: public function setWidthStyle($widthstyle)
• Parameters:
  • $widthstyle

setWidths()

• Signature: public function setWidths($widths)
• Parameters:
  • $widths

wordWrapTable()

@param array of array of string $table_data a row/col array of the text we want in the table

• Signature: public function wordWrapTable($table_data,$font_size,$pad_cell_height)
• Parameters:
  • $table_data
  • array $font_size if $font_size[$i] describe the font_size to be used for row $i. if $font_size[$i] is numeric then the font size applies to the whole row $i. othwise, if it is an array of numeric, the font_size[$i][$j] is the font size of cell $i,$j.
  • boolean $pad_cell_height
    (Default true) whether or not we should ensure that for each table row, we have the same number of rows of text per cell
    • Default Value: true
• Returns: a
  row/col indexed array of arrays. each text cell becomes an array of strings, each element of which is a row of text of that cell.
