90 * Formats rows of a table for text output.
92 * This utility class formats tabular data, mainly for console output.
93 * Each row in the table can take multiple lines, and automatic text wrapping
94 * is supported. If text overflows the allocated width, the remaining columns
95 * on that line become shifted. To avoid this, it is possible to start the
96 * output for different columns from different lines (it is the caller's
97 * responsibility to check that overflows are avoided or are acceptable).
99 * Column definitions are first set with addColumn().
100 * To format a row, first call clear(). Then call addColumnLine() to add text
101 * to each column (can be called multiple times on a single column to add
102 * multiple lines), and possibly setColumnFirstLineOffset() to adjust the line
103 * from which the column output should start. Finally, call formatRow() to
104 * obtain the formatted row.
106 * A header (column titles and a horizontal line) is printed before the first

186 * Adds text to be printed in a column.
188 * \param[in] index Zero-based column index.
189 * \param[in] text Text to add.
191 * Can be called multiple times. Additional calls append \p text as
192 * additional lines. Any calls with \p text empty have no effect.
193 * To add an empty line, use "\n" as \p text.
195 * If \p text contains newlines, the text is automatically splitted to
196 * multiple lines. The same happens if automatic wrapping is on for
197 * the column and the text contains lines that are longer than what
