Data table should render properly on browser resize.

I have a very similar issue, with a ngx-datatable inside a bootstrap tab. The columns get all condensed/shrinked at the beginning of the table. If I simply resize de browser window, the table show correctly again. Problem Doesn't happen outside of tabs.

Anyone find a work around for this? I'm also hitting this issue using bootstrap tabs.

Not really a solution, but a quick hack to fix that could be to send a resize event on the window instance once data is loaded.

My PR #1561 should fix this issue

I think I'm running into the same problem. I'm using Material tabs. My table is selectable with checkboxes as well and highlights rows on mouseover. There seems to be flickering on mouseover at some points as well.

Table version: 14.0.0
Angular version: 6.1.2
Material version: 6.4.5

When you have two tabs, each with a table inside it, and you resize the window, the visible table is recalculated, and is correctly rendered, but the non-visible one in the other tab, is also recalculated but the width of the columns is completely squashed. Then you switch tabs, resize again, which makes the incorrect table show correctly, but now the other table is squashed, etc..

1561 should really, really be merged.

Same for me... I'm subscribing to a hierarchical parent object on a "smart component" and passing the parent's data partially to the table as "dumb component". So it is quite possible that the table recalculates during another mat tab is displayed. When returning to the table tab, the table is empty (really empty, also no messages) until I zoom or somehow else make it rerender.

Hi guys, with help of @Moulde's idea, I believe I have a hacky solution!
First, you need to listen for the selectedTabChange event. Like this:

<mat-tab-group (selectedTabChange)="onTabChange($event)">

Then, on the onTabChange function, you need to fire the Window Resize event forcefully.

onTabChange(event: MatTabChangeEvent) {
        window.dispatchEvent(new Event('resize'));
}

And voilà! Its working fine for me!

[Moulde]

While that hack works, it causes the table to "twitch", every time you switch to the tab, instead of only when necessary, but I do agree that a little twitching every time may be better than a broken table sometimes.

Additionally, the above hack could be further extended to only fire the resize event on tab change IF the data has been reloaded while away from the tab, as, the reload of data for a table while the table is hidden, is what triggers the issue, at least in my case.

Any planned date on getting this fixed in ngx-datatables. Even though the hack works. I don't want to keep it as a permanent solution.
