Hello Ralf.

Thank You for Your purchase.

I am sorry to disappoint You, but unfortunately, the way You have it configured is the only way You can configure it for now (custom CSS).

To change a certain column, You'd have to find it's td. Something like this:

.wpdt-c td.column-gstekategorie {
    text-align: left !important;
}
.wpdt-c td.column-kurabgabe {
    text-align: right !important;
}

The final result would look like in the attachment.

You'd still need to change the header alignment, like You already did.

Please let me know if this works for You.

Best regards.

Hello Ralf.

This error refers when there are some changes in the file from which table is created.

Can You please tell me if You changed something directly in the database? Column name, type, content, did You add something? Whatever comes to mind.

Custom CSS wouldn't be considered a change in the database, though.

As for adding the alignment options to the plugin - we carefully follow customers requirements and try to implement most of them if they appear in requests from time to time, so we will add to our idea list and look into some possible solutions on plugin side in the future.

Best regards.

Hello again Ralf.

I saw that there are three !important statements that cannot be overridden if You add left !important. Please take a look at the attachment. You'd need to disable the tablewrapper text-align, and align each column individually.

Please let me know if You got it to work.

If not, could You please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. You can write credentials here just check Private Reply so nobody can see them except us.

Best regards.

Hey Ralf.

If I understood You correctly You'd like this to be achieved:

1 - You'd like all column headers to be centered, correct? If so, the code is:

/* Für Tabellenüberschriften */
.wpDataTablesWrapper table.wpDataTable thead tr th {
    text-align: center !important;
}

2 - For "Gastkategorie" column, You want the rows to be aligned to the left:

/*Tabelleninhalt  Gastkategorie */
.wpdt-c td.column-gastkategorie {
    text-align: left !important;
}

3 - For "Kurabgabe" column, You want the rows to be centered:

/*Tabelleninhalt  Kurabgabe */
.wpdt-c td.column-kurabgabe {
    text-align: center !important;
}

4 - For "Saisonzeiten" column, the rows should be centered:

/*Tabelleninhalt  Saisonzeiten */
.wpdt-c td.column-saisonzeiten {
    text-align: center !important;
}

5 - For "vom" column, rows centered:

/*Tabelleninhalt  vom */
.wpdt-c td.tblSP_vom.column-von {
    text-align: center !important;
}

6 - For "bis" column, rows centered:

/*Tabelleninhalt  bis */
.wpdt-c td.column-bis {
    text-align: center !important;
}

7 - For "EG 1. Tag" column, rows centered:

/*Tabelleninhalt  EG 1. Tag */
.wpdt-c td.column-eg-1-tag {
    text-align: center !important;
}

8 - For "EG ab 2. Tag" column, rows centered:

/*Tabelleninhalt  EG ab 2. Tag */
.wpdt-c td.column-eg-ab-2-tag {
    text-align: center !important;
}

9 - For "OG 1. Tag" column, rows centered:

/*Tabelleninhalt  OG 1. Tag */
.wpdt-c td.column-og-1-tag {
    text-align: center !important;
}

10 - For "OG ab 2. Tag" column, rows centered:

/*Tabelleninhalt  OG ab 2. Tag */
.wpdt-c td.numdata.integer.tblSP_OG2.column-og-ab-2-tag {
    text-align: center !important;
}

It's all in there, in the Custom JS and CSS field under main Settings of wpDataTables, I just broke it in here like this in case You want to change settings for a certain column. For example - I wasn't sure if You'd like the "Gastkategorie" column's header to be centered or not, but I believe I got it right.

Please check this and let me know if this is what You were looking for.

Best regards.

Hello Ralf.

Thank You for Your kind words. My German is quite basic and a bit rusty, but since You already had Tabellenüberschriften in the description I guessed that for content it had to be "inhalt", and Google Translate confirmed my suspicion. :-)

When You inspect the page, .wpdt-c is just a selector that encloses the entire table. Everything regarding wpDataTables is inside this selector, and it can be found in the beginning of the element when You inspect the page, above that "ugly blue line of code" (see attachment).

When You add it before any custom CSS it applies to the whole table no matter of the position. We know this because we use it on daily basis.

Please feel free to reach out to us if You have any more questions or issues.

We'd greatly appreciate it if you could take a minute and leave a Review on CodeCanyon on this link. Thanks! 

Best regards.
