I have a problem with DataGrid in gwt 2.4. I made table with CellTable, and everything worked fine. But I needed fixed header, and then just replaced CellTable with DataGrid. I had problem with .css file, but than has been resolved.
Now, the problem is that every column have fixed width, and table put every row just in visible part of screen.
This is new and old screen shots, to make things more clear :)

Can someone help to make old looking, but with fixed header.
You can set a fixed width for each column of the data grid:
dataGrid.setColumnWidth(sampleColumn, 40, Unit.PX);
and expand the total data grid width:
dataGrid.setWidth("100%"); // choose the most useful in your app
dataGrid.setWidth("1400px");
I'm not sure what the right answer is, but I don't think the previous responders understood the question.
Basically, you want dataGrid to use "table-layout: auto" instead of "fixed". This is what cellTable does. Table columns are auto-sized based on content.
This is easy for the content table, but to get the header-freeze, dataGrid is using a separate div/table for the header. Therefore, the header table's columns need to be explicitly sized based on the data table. They also need to be resized anytime the table changes (browser resizes, etc.). I plan on adding resizeable cols on a dataGrid, so I'll be hitting this same challenge soon I expect and will update when I have something more explicit if anyone is still tracking this thread...
need to wrap your content in your td with an inner div. and make sure the overflow-x is set to hidden.
table {
overflow: hidden;
white-space: nowrap;
table-layout: fixed;
}
td div{
overflow-x:hidden;
}

Recently started working on a master detail structure angular ag-grid. The structure has two levels of master-detail nesting. I need to fix the heights of inner - 2 grids such that they occupy all available real estate on the screen. Currently, ag-grid defaults it to 300 px and a lot of whitespace or unused space appears on a 1920x1200 screen resolution monitor. I also need to have fixed headers for all grids.
Any ideas or pointers would be appreciated...
Update: Referring to a forked version of plunker example from ag-grid here - https://next.plnkr.co/edit/yUzo4EqONEmgCmIw This is simple and basic set up for master-detail grid.
Note that: I haven't set any detail row height and have setup just one record to show up in the grid to test for the issue.
If you run the plunker code and view the result in separate window, notice that the inner / child grid doesn't occupy all the space available below it. In other words, it doesn't take as much as space/height available from parent container (master's detail row). The default 300px master detailRowHeight is making height fixed for inner grid. Also, from documentation, detailRowHeight prop doesn't seem to take something similar as 100% or 100vh and only takes fixed pixels number. Added a picture of the example below and the height / unused space I referred
We have different resolutions that users use to view data in grid and the heights of inner grids need to auto-adjust taking max. available space to show most information in the grids.
You could try something like this, I pulled it from the documentation:
In your component.ts file add this method. If it's a detail row it will apply different calculations than the other rows.
public rowHeight(params) {
if (params.node && params.node.detail) {
var offset = 80;
var allDetailRowHeight = params.data.callRecords.length * 28;
return allDetailRowHeight + offset;
} else {
// otherwise return fixed master row height
return 25;
}
};
In your template add the following: [getRowHeight]="rowHeight"
<ag-grid-angular
#agGrid
style="width: 100%; height: 100%;"
id="myGrid"
class="ag-theme-balham"
[columnDefs]="columnDefs"
[masterDetail]="true"
[detailCellRendererParams]="detailCellRendererParams"
[getRowHeight]="rowHeight"
[rowData]="rowData"
(gridReady)="onGridReady($event)"
></ag-grid-angular>
Hopefully this will get you moving forward. Good Luck!

So I don't have a great, full solution for you but as a starting point I would use CSS to override the styles ag-grid is setting - I don't think detailRowHeight is going to help.
Here's my plunk getting close to what you want with some simple CSS I put in index.html. You can use !important to override ag-grid styles, or you could use javascript to set the CSS after ag-grid does. I prefer !important in this case and don't have to worry about timing.

The problem I wasn't going to get into is getting it to dynamically fill up available space, depending on the row selected, scroll position, etc. I can't think of any simple way to achieve that - I do this type of thing in grid often and end up writing javascript to calculate the available space, and then set the CSS in javascript.
In ag-grid you have the possibility to set auto height for details.
Set grid property detailRowAutoHeight=true to have the detail grid to dynamically change it's height to fit it's rows.
const gridOptions = {
// dynamically set row height for all detail grids
detailRowAutoHeight: true,
// other grid options ...
}
However if you are providing your own detail component...
detailCellRenderer: 'MyOwnDetailsComponent',
then, it might not work and you will still need to provide an grid options height detail content through...
detailRowHeight: 560,
Please see the ag-grid documentation here
I'm trying to manipulate the style of a data-table being used with ag-grid plugin. The background colour of each row seems to cut off before the end of the table when it's inside of a CSS overflow parent. What can I do to avoid that cut off so that everything is in colour?
I had the same issue and solved it by
using overflow: auto on ag-body-viewport class and remove width: 100% on the .ag-body-container{} class, in case you have that.
I am using bootstrap in an Ruby on Rails app. I use Firefox. I find that the height of the dropdown field (select tag) is too small.However the height of the text fields are appropriate. I had too add the below code to application.css to fix it:
select {
height: 38px !important;
}
Now dropdown shows its content properly though its overall height (box) is a bit bigger that text fields. Is there a neater way to fix the issue?
I found it more appropriate to remove styling from application.scss and modify the app/assets/stylesheets/custom.css.scss instead. custom.css.scss is generated by Bootstrap. The padding for all FORM elements was set to 10px in that file. I set padding for SELECT element to 2px and left the rest intact.
I am using a Gwt DataGrid with multiple Columns. The default behavior of the columns is to wordwrap. I would like for one of the columns to not wordwrap and just cut off. Is this possible?
For example, currently this is displayed:
I am making a
sandwich
I would like it to display:
I am making a
In addition to overflow:hidden you may need white-space:nowrap and finally add a text-overflow: ellipsis so there is an indicator to the user that the incomplete text is being shown.
You can set overflow: hidden in the style of each Column.
You can use DataGrid.addColumnStyleName to set styles on individual columns, or just addStyleName to add a style to the whole widget.
I am using a CellTable on a ScrollPanel in GWT. My table has two columns and I want to give 10% and 90% of the width each. This is fine.
The problem is that I want to have one line of text per row in the table. That is if the content of one cell is too large to be showed in one line, I want to have either a horizontal scrolling bar or just truncate the text to fit it in one line.
Here is an extract of my code:
cellTable.addColumn(column1);
cellTable.addColumn(column2);
cellTable.setWidth("100%", true);
cellTable.setColumnWidth(column1, 10.0, Unit.PCT);
cellTable.setColumnWidth(column2, 90.0, Unit.PCT);
I also tried to use:
cellTable.setTableLayoutFixed(true);
but it doesn't change the layout.
Thanks a lot for your comments!
Use the CSS property "white-space: nowrap"

You'll have to play with the word-wrap, overflow and possibly text-overflow CSS properties.
