The table's (Auto Width) AutoWidthType property indicates how the reporting tools should modify the width of the cells after rendering the report.

 none

Column widths are set according to the contents of all table cells (the longest line is taken per column). If the FixedWidth property is set to true, the columns will not resize.

 Full Table

Column widths are set according to the width of the table. In other words, all column cell widths are checked first (column widths are set by the longest row). If there is free space, it is distributed equally among all columns. If there is not enough space to print the longest line, the column width is reduced equally across all columns.

 Last Columns

Column widths are set according to the width of the table. In other words, all column cell widths are checked first (the column width is set by the longest row). If there is free space, it will be distributed to the last column whose FixedWidth property is set to false. If there is not enough space to print the longest line, the width of the last column is reduced and distributed across all columns that have their FixedWidth property set to false.
