Fiori Element List Report – Adjust column size automatically
You may know that ALV columns width can be adjusted automatically depending on the content size :
This is a cool feature that is unfortunately not available in List Report Fiori Element. There is an option that is activated by default but the behavior is different : SAPUI5 Documentation
The column width is defined according to element theorical length, not the actual length of the content (please note that I’m focusing on List Report in Gridtable mode (not reponsive table).
Edit 22/09/2020 : See Tim comment below, it also works with analytical table, you juste have to get the id of “analyticalTable” instead of “GridTable”.
See example below :
To reproduce ALV behavior, you will have to implement an extension to your fiori element.
1. Declare the controller extension in the manifest.json
"extends": {
"extensions": {
"sap.ui.controllerExtensions": {
"sap.suite.ui.generic.template.ListReport.view.ListReport": {
"controllerName": "<your_namespace>.<your_app_name>.ext.controller.ListReportExt"
}
}
}
},2. Add the controller file to your app
3. Add the code below to your controller
sap.ui.controller("<your_namespace>.<your_app_name>.ext.controller.ListReportExt", {
onInit: function (oEvent) {
if (!this._sIdPrefix) {
this._sIdPrefix =
"<your_namespace>.<your_app_name>::sap.suite.ui.generic.template.ListReport.view.ListReport::<ENTITY_NAME>--";
}
},
onAfterRendering: function (oEvent) {
var oContentTable = this.byId(this._sIdPrefix + "GridTable");
oContentTable.attachBusyStateChanged(this._onBusyStateChanged);
},
_onBusyStateChanged: function (oEvent) {
var bBusy = oEvent.getParameter("busy");
if (!bBusy && !this._bColumnOptimizationDone) {
var oTable = oEvent.getSource();
var oTpc = null;
if (sap.ui.table.TablePointerExtension) {
oTpc = new sap.ui.table.TablePointerExtension(oTable);
} else {
oTpc = new sap.ui.table.extensions.Pointer(oTable);
}
var aColumns = oTable.getColumns();
for (var i = aColumns.length; i >= 0; i--) {
oTpc.doAutoResizeColumn(i);
}
//This line can be commented if you want the columns to be adjusted on every scroll
//this._bColumnOptimizationDone = true;
}
}
});This post helped me : Stackoverflow
4. And voilà !
If someone knows a way to do this without extension please let me know in the comment section.
EDIT : sap.ui.TablePointerExtension is not available in the newest version of SAPUI5. I adjusted the code to make it work in old and new versions.
Thank you,
It works, but after click on setting button, either cancel or ok, the columns are back to original.
How do we achieve auto width after settling buttons click.
Sai.
Hello,
In my case, when I change the settings, the data is refreshed so the columns are optimized again.
Hey Louis-Arnaud,
does it also work with an AnalyticalTable? Nothing happens in my App.
regards
Hello Tim,
I didn't try with Analytical table, I guess that you need to change this line to get the right objet :
Maybe it is as simple as changing GridTable by AnalyticalTable. Or you may need some debugging to undestand what need to be changed.
I wish it would be working with changing the line. But not.
This is the error in the console.
You need to find the id of the Analytical table to get the object with this.byId().
Hey,
thanks, it works very good in my Analytical List Page with analytical table.
please note that the initial letter must be written in lower case. I had always written "AnalyticalTable".
regards
Another way of doing this is from SAP Visual Editor. I normally use this to freeze my column widths for Analytical or Grid Table. Go to Visual editor in your UI5 project, Select edit mode, Select column and manually enter the width based on the character length. Generally measured in 'em'
In this case, the Auto is ignored and manual entry is considered always.
I also do kind of the the same way, but instead of you, I set the width property to auto and the Min Width to 100 pixels or whatever is needed for the specific column.
That way on larger screens it always gets the entire table and on smaller screens you can always see the information of that column.
If you don't want to do extensions, and there are not so much columns just go and create a new default layout... adjust the columns to your liking... and transport. Choose all 3 options.
Where can we see the sap documentation for sap.ui.table.extesnions.pointer?
Dear Louis-Arnaud BOUQUIN,
Code;
var oTpc = new sap.ui.table.TablePointerExtension(this._oTable);
for (var i = 0; i < this._oTable.getColumns().length; i++) {
oTpc.doAutoResizeColumn(i);
}
Works fine with version '1.52.45', but throws the below error with version '1.84.6',
TypeError: sap.ui.table.TablePointerExtension is not a constructor
Could you help me here to understand the issue and a fix to be applied.
Thank's

Hi,
Your solution worked like magic.. thanks for the information.
I have tried the below approach as well to set the default column width, its static length.
Setting the Default Column Width
Thanks
