Tells FlexCel that it must try to keep together the columns between col1 and col2 (inclusive) when printing. This method does nothing to the resulting Excel file since this is not an Excel feature. To actually do something, you need to call TExcelFile.AutoPageBreaks after calling this method.
procedure TXlsFile.KeepColsTogether(const col1: Integer; const col2: Integer; const level: Integer; const replaceBiggerLevels: Boolean); override;
|const||col1||Integer||First column of the group you want to keep together.|
|const||col2||Integer||Last column of the group you want to keep together.|
|const||level||Integer||Set this parameter to 0 to remove the condition to keep columns together. Any bigger than zero value will mean that the rows must be kept together. You can use more than one level to tell FlexCel to try to keep different groups together, If all columns cannot be kept together in one page, FlexCel will try to keep as much columns with higher levels as possible. See the example for more information.|
|const||replaceBiggerLevels||Boolean||If true, all existing level values in the column range will be replaced. If false, the new level values will be written only if they are bigger than the existing ones. You can use the false setting to set many values in any order.
For example, if you first call KeepColsTogether(2, 3, 5, false) and then KeepColsTogether(1, 10, 1, false), columns 2 and 3 will keep the level in 5. If you did so with this parameter true, the second call would replace the levels of columns 2 and 3 to level 1, making all column levels between 1 and 10 equal to 1.
If you call:
xls.KeepColsTogether(1, 10, 1, true); xls.KeepColsTogether(3, 4, 2, true);
This will define two groups. FlexCel will try to keep columns 1 to 10 in one page. But if this is impossible, it will try to keep at least columns 3 and 4 together.
Values of the "level" parameter mean the strongness of the link. Columns with higher level values have a stronger link, and if it is impossible to keep all columns together, FlexCel will try to keep the higher level columns.
In this case, Columns 3 and 4 have a higher level, so if columns 1 to 10 cannot be kept together in one page, FlexCel will try to keep at least columns 3 and 4. Normally you will want to use higher level values completely inside groups with lower levels. If we called:
xls.KeepRowsTogether(1, 10, 1, true); xls.KeepRowsTogether(3, 4, 1, true);
The second call would do nothing, since the level is the same, and columns 1 to 10 are already linked.
