My table has a large number of columns. By default, I only display a small subset.
Using the button extension colvis, I am giving the user three options to change column visibility. Two colvisGroup buttons and one colvis button that allows control over the visibility of each column individually.
{
extend: 'colvisGroup',
text: 'Summary Columns',
show: [ 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 ],
hide: [ 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45],
},
{
extend: 'colvisGroup',
text: 'Detail Columns',
show: [ 3, 11, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44],
hide: [ 4, 5, 6, 7, 8, 9, 10, 12, 13, 14, 45 ],
},
{
extend: 'colvis',
collectionLayout: 'fixed two-column',
columns: ':not(.noVis)',
postfixButtons: [ 'colvisRestore' ],
}
My table also highlights some cells' values if certain conditions are met via a rowCallBack. Whenever a user changes column visibility, I have to draw the table to ensure that the correct cell values are highlighted. Therefore I added an event handler for column-visibility.dt, but unfortunately for the colvisGroup it fires for each of the columns to be shown slowing down the display of the table.
$('#hrifcpq').on( 'column-visibility.dt', function ( e, settings, column, state ) {
tablehrif.draw();
} );
I am looking for a modification to my event handler that would function more like this:
$('#hrifcpq').on( 'column-visibility.dt', function ( e, settings, column, state ) {
if (user clicked on colvis button) tablehrif.draw();
else if (user clicked on colvisGroup button) {if (column == hriftable[0].length-1-3) {tablehrif.draw();}}
} );
Is this possible?
Is there another way to trigger the rowCallBack besides listening to the column-visibility.dt event?
Please let me know if you have a suggestion, thank you!
