Using phpMyAdmin: can one alter a table's schema by inserting new columns, as one would using spreadsheet software? Like when one creates a new table.
If you click the Structure tab you'll be able to affect the columns or add in new ones.
To edit existing columns
Check the box on the left of the columns
Click the pencil icon below the structure display.
The next screen will allow you to adjust the column properties of those selected.
To add in new columns
Look below the table structure display
Enter however many new columns, and where in the table they'll go
Click Go.
The next screen will allow you to enter the properties for each of the new columns for the table.
If you select all at the bottom of the screen below the table,then click change, you can change them all like you did when first creating the table.

I am stuck and don't know how to get this operation with Qtablewiget, I have a Qtablewidget which displays data in three columns (data is displayed on cells containing QlindEdit). At start when Qtablewidget appear, I want the very first cell (with QlineEdit) should get focus and then I can use downarrow key to move to every column cell containing QlineEdit. My QTablewidget has 10 rows and 3 columns, everycell in columns contain QlineEdit widget. I want when the focus reach to last cell of column via downarrow key, it should move to first cell of second column in tablewidget. I don't know to to achieve this.
Can anyone tell me the solution or share any example related to the solution as reference, I will be very helpful for me. I have shared screen shots of my table and the table I want to create like.
Thank you in advance!

I am trying to create a Table that shall contain some columns with basic facts on the left and on the right side there shall be some columns that can be tabbed. Something like this:
So the Question is, how to do this?
I could personaly think of two solutions, but I actually don't like both:
Write a own Table for Tab1,Tab2 ... That contains the basic data and the Tabbed Data
Write a Table for the basic Data and one for each Tab. Here I think you would have a lot of Design problem "glueing" both tables together, so they look like one table.
So actually I don't like both solutions. Maybe there is a better solution to this?
Perhaps you could give the columns that belong to each tab their own unique class, e.g. .tab1-columns, .tab2-columns, etc. Then, you could show or hide the column depending on the active tab. The tabs, however, would exist outside of the table. Alternatively, you could pt the tabs into a pseudo- header row above the actual table header row, with the first header cell spanning those cells that shouldn't be "tabbed". However, I believe leaving the tabs outside of the table would be a bit more semantic in nature.
HTH.
Render all columns but hide them (display: none;) except the column by default.
Then add an click event on the tabs to switch the visible columns. be sure to use just the nav-tabs and not the js component.. it will be easier I think
I have check boxes in the far left hand column in a table and would like to use these to perform batch edits on the contents of the table. For example a user would like to edit multiple items in the table: They check the ones they want to edit, and then go to the drop down at the bottom of the table to select what they'd like to change one of the columns to. When they hit submit I would check for boxes that are checked and modify the associated columns. The image below shows this visually.
The checkboxes I are not in any and are solely checkboxes. I'm assuming this is the correct thing to do as I do not the whole table being part of the form. My question then is, how would I submit the checkboxes when "Submit" is pressed, so that I can check which checkboxes are used?
Move the form tag to the top of the table and then the checkboxes will be included in the POST request.
I am having HTML Tables. There are 10 columns inside that table. I want to Drag and Drop more than one columns. (i.e) select multiple columns and move them around (change column ordering)
Drag and Dropping a single column i know, but how to do this with Multiple Columns...
I am not pretty sure about the code but,
I guess there is one thing that you can try
When the user wants to move the columns then ask him to generate an event like(click on a button or something) now you know when the the particular button is clicked. Now ask the user to select the columns by clicking on them one by one when all the desired columns are selected put them in a single column and ask the user to move it. when the user drops this column on desired location you can remove this column.
How can I simply move a table column left or right in Report Builder using the UI (or text editor if necessary)?
I've tried to drag and drop, looked at menus, etc, and I can't find that option. Is it in there? So far I've had to delete and recreate a column every time I wanted to change its position.
In Report Builder 3.0 you can move columns like this:
Insert a new empty column
Copy (or cut) the text of the header and the text of the value in the new empty cells
Delete the old column
Or the easiest way is just to not move the columns but change their content by hovering over the column you want to change and select a new data type. After this you still need to update the column name and you're done.
I tried this too, but it only moves the values in the DataSet, not in the report:
Right click DataSet1 in the left menu and select Dataset Properties
Select Fields on the left and click on any field to move it with the blue arrows on top
You can cut and paste - click the column you want to move and cut with Control-X. Then select a different column and paste with Control-V. That will place the old column to the left of the selected column.
