Fixed columns disappear when scrolling down to the bottom of the rows

kakacek

Hello, I am trying to accomodate the DataTablesn and the FixedColumns plugins. Ignoring the fact that it is quite slow even on my i7/8GB MBP, everything seems to work, except of one issue:

When I scroll down the rows, almost down, the fixed columns dissapear.

To better understand me, I am adding the links to the two images - the first one shows the look just after the load of the page - and the second shows it after I scroll down...

The only way how to re-display the fixed columns is to refresh the page...

The component initialization code looks like this:

[code]$(document).ready(function() {
startListTable = $('#dataTable1').dataTable( {
"aoColumns": [
{"sTitle":"ID","sClass":"left","bSortable": true},
{"sTitle":"Příjmení","sClass":"left","bSortable": true},
{"sTitle":"Jméno","sClass":"left","bSortable": true},
{"sTitle":"Ročník","sClass":"left","bSortable": true},
{"sTitle":"Klub/Město","sClass":"left","bSortable": true},
{"sTitle":"Zaplaceno","sClass":"left","bSortable": true},
{"sTitle":"Registrace","sClass":"left","bSortable": true},
{"sTitle":"Trať","sClass":"left","bSortable": true},

}
},
"fnRowCallback": function(nRow) {
if(nRow.cells[2]) nRow.cells[2].noWrap = true;
return nRow;
}
} );
new FixedColumns(startListTable, {
"iLeftColumns": 4,
"iLeftWidth": 350
} );
} );[/code]

Can you link to a test case showing the issue so I can reproduce and fix the issue please? Can you also try it with the latest 2.5.0-dev code for FixedColumns.

It is a bit hard to publish it alive as I CANNOT publish it while it does not work...

So I created the static extract which behaves that bad and published it here:

Thanks for the link. I see what the problem is - you are using infinite scrolling with FixedColumns, which is not supported. I'll look at adding a warning to FixedColumns to specifically say that it will not work. Sorry.

Thank you for your response - I understand.

BTW: I think that was visible from my original post...

Anyway thank you again for your effort.

Please consider this bug report as closed (as a feature not a bug)...

Yes it was visible from your original post, but I missed it. My apologies.
